Nice! But it doesn't recognize marquee as a valid tag
- codingdave 2y ago
  It isn't valid. It is deprecated. Just like <blink>. But to be fair, the page doesn't specify which HTML standard we're working with.
  - wongarsu 2y ago
    HTML5 says it "must not be used by authors", but it still describes it as a tag, and describes what an implementation must conform to. I guess it's open to interpretation what "valid" means. But it is an HTML tag described by the HTML standard (both HTML5[1] and the WhatWG HTML spec [2]) [1]: https://www.w3.org/TR/2011/WD-html5-20110405/obsolete.html#the-marquee-element https://www.w3.org/TR/2011/WD-html5-20110405/obsolete.html#t...

  - TonyTrapp 2y ago
    To be clear: Neither blink nor marquee were valid tags under any HTML standard. They always were non-standard browser extensions.
    - mynameisvlad 2y ago
      It's a "non-conforming feature" but it's still a part of WhatWG's standard as obsolete, including what it should render as: https://html.spec.whatwg.org/multipage/rendering.html#the-marquee-element-2 https://html.spec.whatwg.org/multipage/rendering.html#the-ma... and https://html.spec.whatwg.org/multipage/obsolete.html#the-marquee-element https://html.spec.whatwg.org/multipage/obsolete.html#the-mar...

It's funny, I've been working with HTML since 1998, and I got 36 (though I do think <font> should've been allowed). I thought I'd do a lot better, but I guess you can accomplish a lot with only a few tags, CSS, and some minimal JavaScript.
- alberth 2y ago
  I got to 41. What helped is remembering an entire "block" of tags e.g. H1 would also mean H2-H6 (I'll be the first to admit I really struggled to get to 41 and I too have been writing HTML by hand since 90s)

I got to 57 before running out of tags that I use at least once a year. Had an "Oh yeah" moment when I realized that I'd forgotten html, head, title, body, script, style, and meta.
- KTibow 2y ago
  Somewhat similar experience, except I started with those and somehow forgot about headings and images.
grose 2y ago
I wonder what the most "obscure" tag is. My vote goes to <base>.
- gushogg-blake 2y ago
  I was at least vaguely aware of <base>. No idea what <samp>, <track>, <dfn> or <del> do. Also apparently <ruby> is not for embedding Ruby scripts: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/ruby https://developer.mozilla.org/en-US/docs/Web/HTML/Element/ru...

  - grose 2y ago
    <samp>, <var>, <kbd> are definitely weird ones. Maybe <kbd> would be more useful with some better default styling. I think <output> has some accessibility wins but I've never seen someone use it. <dfn> is a good pick, <abbr> is also up there with questionable semantic tags. <del> and <ins> are basically tailor-made for rendering diffs. <ruby> is really useful for Japanese, doing that styling manually would be a huge pain, but niche for sure. I'm happily surprised <small> survived. I still miss <center>.
    - j1mmie 2y ago
      <dfn> - I was going insane trying to remember that one! I tried <def>, <definition>, <define>...
      - lucgommans 2y ago
        I tried the exact same three! Eventually gave up on that path, thinking "I could swear HTML had some way to have a glossary...", and of course seeing it does after revealing the answers

TIPSIO 2y ago
In HS we were learning basic HTML and I did not care at all at the time. The teacher had us build a page with like 10 tags or something. I thought I was clever and quickly wrote out: h1 h2 h3 h4 h5 h6 h7 h8 h9 h10 Needless to say he told me to figure out why I needed to redo it.

I swear Google has published a report from their crawl data about how in/frequently different tags and frameworks were used, in part to determine what they might need to support in Chrome. I'm not able to find this anymore. Does anyone know what I'm talking about?
- alberth 2y ago
  Given that DIV seems to be the only tag frameworks use the last 10+ years, such a report is not surprising.
  - seattle_spring 2y ago
    What do you mean by that? I know a lot of devs just blast div everywhere, but frameworks? Which ones?
- phil-pickering 2y ago
  This is the one that Hixie published back in 2006. It helped guide a lot of the early decision-making in the WHATWG when it came to proposing new tags for HTML5 in a bid to reduce the number of div's out there: https://web.archive.org/web/20060203035414/http://code.google.com/webstats/index.html https://web.archive.org/web/20060203035414/http://code.googl... The mantle has now been passed to the HTTP Archive, whose Web Almanac includes a section on the popularity of HTML elements: https://almanac.httparchive.org/en/2022/markup#elements https://almanac.httparchive.org/en/2022/markup#elements BTW: I got 97, which is 96 more than the number of friends I have :)

I would love to see an "I give up button" that tells you what you missed. I got to 80, and I'm stumped on the last 34.
sircastor 2y ago
I managed to get 50 unassisted. Now looking at these comments I'm amused at some obvious ones that I missed. I've been writing html since ~1995 (I think) and I was surprised that <frame> didn't work. It was all the rage back in the day.
saurik 2y ago
(edit: Multiple people have interpreted this comment in a way which makes them think I'm complaining about the semantics and one even seems to think I am "advocating for" using the wrong semantic... I am merely complaining about the chosen tag name and how much longer the much-later-added tag we all are supposed to use is than the tag which is in some sense--not technically, but morally--deprecated, as it undermines being able to use HTML as a true markup rather than a rendering target. If you find yourself thinking I'm against using <strong> and are somehow pro-<b>, maybe re-read the comment or go read some of my other much-longer explanations I've been <strong>-armed ;P into providing down-thread. FWIW, I do at least see how my comment was a bit confusing.) Doing this reminded me how angry I am that I am supposed to use "<strong>...</strong>" instead of "<b>...</b>". The verbosity overhead in a normal document of markup littered with five-character tags for something as basic as a keyword is sufficiently worse than one-character tags that it drives me to want to use something like Markdown (but then I am angered that it went with *...* and **...** instead of /.../ and *...* and I just start to give up on other peoples' tooling entirely).
- catapart 2y ago
  "bold" is a style, and perfectly fine to use for any word that you want to apply that style to. "strong" is an intention and allows other things to define what style(s) that intention should be represented with. It's not often that you want to represent something as a "bold" style without representing it as having strong emphasis, but there are times. A header is a good example of a place where you might want the header to be styled bold, but strongly emphasize a single word in the header. Since <header> doesn't apply the styles that - say - h1 does, it would be perfectly reasonable to script your header as ``` <header><b>The <strong>Worst</strong> Case Scenario</b></header> ``` ... especially if you didn't want all of your headers to have a bold style applied. Obviously there are a few other edge cases but I will admit that the vast majority of the times would naturally call for a strong tag, over a bold tag. And for those majority cases, I'm really glad that it's "strong" rather than bold, because "strong" is meaningful in different ways than "bold" and it always makes more sense, to me, reading it back as html telling me how I should interpret the word, rather than just how it should look.

I got to 63, I think mainly because I've been working on an HTML5 pretty-printer in Racket recently [1] (basically my own implementation of the formatting aspects of HTML Tidy). [1]: https://joeldueck.com/what-about/html-printer/ https://joeldueck.com/what-about/html-printer/
ygra 2y ago
In hindsight I missed a few obvious ones (completely forgot lists), but would have expected HTML 4 tags to still be HTML tags (font, etc.). And I do wonder why SVG is on that list, which can be used inside HTML, but is pretty much not an HTML element, to my knowledge (same with math).
- hayleox 2y ago
  It's a valid HTML tag indicating that its contents are not HTML but instead SVG. The contents of a <script> tag are also not HTML, but we still consider <script> to be an HTML tag.
  - ygra 2y ago
    It's not just the contents; it's the tag itself. The only thing that is special to my knowledge is that the HTML 5 parser understands it and applies the correct XML namespace. ... Ah, but thinking about it while I type these lines tells me where I'm wrong: It is an HTML element that's by default rendered as a block element, takes part in all the typical layout stuff. I can apply border, border-radius, background, etc. to it and it behaves like a div. Just that I can also put graphics inside.

  <img> also took me the longest time, and <br> even longer though I used it within the last hour, but the facepalm moment came when I almost decided to give up and then remembered <h1> through <h6>.

No love for <marquee> or <center> anymore. Remember, an html tag is only truly deprecated if you stop using it and let it leave your heart.

      I understand your position and that may be correct. I'm not sure. It's so common (so common that it still works everywhere) might be worth an exception.

It looks like the comment tag isn't included. (Not sure whether it should be. Not even sure the proper way to identify it, I suppose a single "!")
- lucb1e 2y ago
  I would have said !-- is the tag name of that, though with the closing part requiring a double dash as well, it's rather unique and maybe not a proper tag... could have included it in a bonus list though, not counting it towards the total but showing it as a bonus entry at the top of your findings

    In html 2.0 the definition makes a bit more sense than what the definition in the newest whatwg spec. https://www.rfc-editor.org/rfc/rfc1866#section-3.2.5 https://www.rfc-editor.org/rfc/rfc1866#section-3.2.5 Basically <!> was valid, and -- only served as the start and end of a comment, and between <! and > you could have multiple "comments", example from the rfc:  In the current spec it is basically defined as starts with "". https://html.spec.whatwg.org/#comments https://html.spec.whatwg.org/#comments

  In the DOM, comment nodes are not elements, they're their own type of node altogether. Their .nodeName is `#comment`, for what it's worth.
jermaustin1 2y ago
I did worse than I thought I would since I've been at this since the late 90s. I blame code completion. I got to 68, and when another tag didn't come to me after 5 minutes, I gave up. <blink> and <marquee> were my first guesses just for fun before I moved on and started with all the single character tags I could think of (a,b,i,p,s,u), then the various document tags (html, head, body, link, style, script, meta), then all the semantics (aside, article, nav, header, footer). Then the old school (table (and the descendants), div, p, span, etc...). It made me realize how many tags I just do not use anymore (object or embed anyone?).
jchw 2y ago
I managed to get just over half-way and recall 58 of them before I ran out. I find it interesting which are omitted. I assume these tags are just fully removed from HTML5, although most of them continue to work just fine with the exception of <blink>. - <blink> - <marquee> - <tt> - <center> - <frame> - <frameset> That said, it accepts both <object> and <embed>, which I found moderately surprising, since I thought that those were mostly only used for ActiveX and NPAPI plugins. Maybe the last major round of deprecations for HTML came just a tad too early to kill them off, or maybe there is more to them than that. Some tags I feel are underrated in handwriting HTML that are still in the spec: <figure> and <figcaption>, good for semantically representing images with captions. <thead>/<tbody>/<tfoot>, semantically segments a table; In theory could be used by assistive technology, or possibly renderers that need to paginate HTML and want the table headers to repeat on each page (does any agent do this?). <picture> + <source>, pure-HTML method of having responsive images in an HTML page, can support a fallback for browsers that don't support it, too. On that note, the srcset and loading attributes of img are very useful too, srcset as an alternative to <picture>, ostencibly aimed at use cases where the different sources are identical aside from pixel density (vs <picture> which is meant to contain potentially more significantly different images for different responsive layouts.) I wonder which things I missed. That would be a nice feature to add. (I know I missed a few table elements because I just thought of colgroup while typing this.)
- mbo 2y ago
  No love for <q>? It does curly quoting!
  - jchw 2y ago
    Wow, that's awesome! I've been remembering the HTML entities for double quotes for so long, I actually had no idea this tag existed. What's even more fascinating about <q> is that it is localized too! Wow! Check it out. If you do... <p lang="en"><q>My English quote</q></p> you will of course get... “My English quote” But, if you do... <p lang="ja"><q>日本語の引用</q></p> Then you get: 「日本語の引用」 Magic! There's only one real problem I have with this: it seems to be implemented on the layout-level using ::before and ::after pseudo-elements, and thus the quotation marks are intangible. That's a real bummer, which has the result of making the quotation marks not able to be copied or selected (and their visibility to screen readers may also be impacted?) So unfortunately, for now, I am going to continue using good ol' ldquo and rdquo. But, that's pretty neat.

Maybe the validator should be something like Object.getPrototypeOf(document.createElement("a")).constructor !== HTMLUnknownElement I noticed several functional HTML elements (like "font") were not in the list, so might be nice to just trust the browser (not sure how you'd get the correct count per browser though).

For amusement, I tried inputting <applet>, <center>, <font>, <marquee>, and <object>, but the form declared them all invalid. I vividly remember using these over a decade ago. There are a few sites still using <frame> and <frameset>, but both are marked as invalid.
- pvorb 2y ago
  <object> works, but I was surprised as well that the others don't. It was really hard for me to come up with many tags that are still allowed.
- TheRealPomax 2y ago
  Correctly: almost all of them were removed from the HTML spec many years ago (but not <object>, that's still a valid HTML5 element). But: invalid according to the spec doesn't mean it won't do something in a browser, browsers aren't pure spec implementations, they're applications used by humans to view content made by humans =)

If you want to see which ones you've missed, put this in the JS console: Els.filter((item) => {return ! Elsguessed.includes(item)}) In Firefox (probably also in other browsers), links in the console are also clickable, so if you want to look any up, printing them as a link may be helpful: Els.filter((item) => {return ! Elsguessed.includes(item)}).map((item) => {console.log(`https://developer.mozilla.org/en-US/docs/Web/HTML/Element/${item}`)}) I got to 80 found / 34 remaining (plus, of course, various deprecated tags and some which I'm very surprised were not deprecated such as map). Of the remaining ones, I've used several in the past and would have been able to say what they do... stupid memory is bad at enumeration!

Many people mention marquee and blink. Neither of those have ever been part of any HTML specification since the dawn of HTML. marquee was inserted into the current version of HTML for the sole purpose of marking it obsolete because so many people were using it (so I was told long ago).

Nice! But it doesn't recognize marquee as a valid tag

codingdave 2y ago
It isn't valid. It is deprecated. Just like <blink>. But to be fair, the page doesn't specify which HTML standard we're working with.
- wongarsu 2y ago
  HTML5 says it "must not be used by authors", but it still describes it as a tag, and describes what an implementation must conform to. I guess it's open to interpretation what "valid" means. But it is an HTML tag described by the HTML standard (both HTML5[1] and the WhatWG HTML spec [2]) [1]: https://www.w3.org/TR/2011/WD-html5-20110405/obsolete.html#the-marquee-element https://www.w3.org/TR/2011/WD-html5-20110405/obsolete.html#t...

- TonyTrapp 2y ago
  To be clear: Neither blink nor marquee were valid tags under any HTML standard. They always were non-standard browser extensions.
  - mynameisvlad 2y ago
    It's a "non-conforming feature" but it's still a part of WhatWG's standard as obsolete, including what it should render as: https://html.spec.whatwg.org/multipage/rendering.html#the-marquee-element-2 https://html.spec.whatwg.org/multipage/rendering.html#the-ma... and https://html.spec.whatwg.org/multipage/obsolete.html#the-marquee-element https://html.spec.whatwg.org/multipage/obsolete.html#the-mar...

I wonder what the most "obscure" tag is. My vote goes to <base>.

I was at least vaguely aware of <base>. No idea what <samp>, <track>, <dfn> or <del> do. Also apparently <ruby> is not for embedding Ruby scripts: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/ruby https://developer.mozilla.org/en-US/docs/Web/HTML/Element/ru...

  <samp>, <var>, <kbd> are definitely weird ones. Maybe <kbd> would be more useful with some better default styling. I think <output> has some accessibility wins but I've never seen someone use it. <dfn> is a good pick, <abbr> is also up there with questionable semantic tags. <del> and <ins> are basically tailor-made for rendering diffs. <ruby> is really useful for Japanese, doing that styling manually would be a huge pain, but niche for sure. I'm happily surprised <small> survived. I still miss <center>.

sircastor 2y ago

I managed to get 50 unassisted. Now looking at these comments I'm amused at some obvious ones that I missed. I've been writing html since ~1995 (I think) and I was surprised that <frame> didn't work. It was all the rage back in the day.

saurik 2y ago

(edit: Multiple people have interpreted this comment in a way which makes them think I'm complaining about the semantics and one even seems to think I am "advocating for" using the wrong semantic... I am merely complaining about the chosen tag name and how much longer the much-later-added tag we all are supposed to use is than the tag which is in some sense--not technically, but morally--deprecated, as it undermines being able to use HTML as a true markup rather than a rendering target. If you find yourself thinking I'm against using <strong> and are somehow pro-<b>, maybe re-read the comment or go read some of my other much-longer explanations I've been <strong>-armed ;P into providing down-thread. FWIW, I do at least see how my comment was a bit confusing.) Doing this reminded me how angry I am that I am supposed to use "<strong>...</strong>" instead of "<b>...</b>". The verbosity overhead in a normal document of markup littered with five-character tags for something as basic as a keyword is sufficiently worse than one-character tags that it drives me to want to use something like Markdown (but then I am angered that it went with *...* and **...** instead of /.../ and *...* and I just start to give up on other peoples' tooling entirely).

catapart 2y ago
"bold" is a style, and perfectly fine to use for any word that you want to apply that style to. "strong" is an intention and allows other things to define what style(s) that intention should be represented with. It's not often that you want to represent something as a "bold" style without representing it as having strong emphasis, but there are times. A header is a good example of a place where you might want the header to be styled bold, but strongly emphasize a single word in the header. Since <header> doesn't apply the styles that - say - h1 does, it would be perfectly reasonable to script your header as ``` <header><b>The <strong>Worst</strong> Case Scenario</b></header> ``` ... especially if you didn't want all of your headers to have a bold style applied. Obviously there are a few other edge cases but I will admit that the vast majority of the times would naturally call for a strong tag, over a bold tag. And for those majority cases, I'm really glad that it's "strong" rather than bold, because "strong" is meaningful in different ways than "bold" and it always makes more sense, to me, reading it back as html telling me how I should interpret the word, rather than just how it should look.

ygra 2y ago

In hindsight I missed a few obvious ones (completely forgot lists), but would have expected HTML 4 tags to still be HTML tags (font, etc.). And I do wonder why SVG is on that list, which can be used inside HTML, but is pretty much not an HTML element, to my knowledge (same with math).

hayleox 2y ago
It's a valid HTML tag indicating that its contents are not HTML but instead SVG. The contents of a <script> tag are also not HTML, but we still consider <script> to be an HTML tag.
- ygra 2y ago
  It's not just the contents; it's the tag itself. The only thing that is special to my knowledge is that the HTML 5 parser understands it and applies the correct XML namespace. ... Ah, but thinking about it while I type these lines tells me where I'm wrong: It is an HTML element that's by default rendered as a block element, takes part in all the typical layout stuff. I can apply border, border-radius, background, etc. to it and it behaves like a div. Just that I can also put graphics inside.

jermaustin1 2y ago

I did worse than I thought I would since I've been at this since the late 90s. I blame code completion. I got to 68, and when another tag didn't come to me after 5 minutes, I gave up. <blink> and <marquee> were my first guesses just for fun before I moved on and started with all the single character tags I could think of (a,b,i,p,s,u), then the various document tags (html, head, body, link, style, script, meta), then all the semantics (aside, article, nav, header, footer). Then the old school (table (and the descendants), div, p, span, etc...). It made me realize how many tags I just do not use anymore (object or embed anyone?).

jchw 2y ago

I managed to get just over half-way and recall 58 of them before I ran out. I find it interesting which are omitted. I assume these tags are just fully removed from HTML5, although most of them continue to work just fine with the exception of <blink>. - <blink> - <marquee> - <tt> - <center> - <frame> - <frameset> That said, it accepts both <object> and <embed>, which I found moderately surprising, since I thought that those were mostly only used for ActiveX and NPAPI plugins. Maybe the last major round of deprecations for HTML came just a tad too early to kill them off, or maybe there is more to them than that. Some tags I feel are underrated in handwriting HTML that are still in the spec: <figure> and <figcaption>, good for semantically representing images with captions. <thead>/<tbody>/<tfoot>, semantically segments a table; In theory could be used by assistive technology, or possibly renderers that need to paginate HTML and want the table headers to repeat on each page (does any agent do this?). <picture> + <source>, pure-HTML method of having responsive images in an HTML page, can support a fallback for browsers that don't support it, too. On that note, the srcset and loading attributes of img are very useful too, srcset as an alternative to <picture>, ostencibly aimed at use cases where the different sources are identical aside from pixel density (vs <picture> which is meant to contain potentially more significantly different images for different responsive layouts.) I wonder which things I missed. That would be a nice feature to add. (I know I missed a few table elements because I just thought of colgroup while typing this.)

mbo 2y ago
No love for <q>? It does curly quoting!
- jchw 2y ago
  Wow, that's awesome! I've been remembering the HTML entities for double quotes for so long, I actually had no idea this tag existed. What's even more fascinating about <q> is that it is localized too! Wow! Check it out. If you do... <p lang="en"><q>My English quote</q></p> you will of course get... “My English quote” But, if you do... <p lang="ja"><q>日本語の引用</q></p> Then you get: 「日本語の引用」 Magic! There's only one real problem I have with this: it seems to be implemented on the layout-level using ::before and ::after pseudo-elements, and thus the quotation marks are intangible. That's a real bummer, which has the result of making the quotation marks not able to be copied or selected (and their visibility to screen readers may also be impacted?) So unfortunately, for now, I am going to continue using good ol' ldquo and rdquo. But, that's pretty neat.

Maybe the validator should be something like Object.getPrototypeOf(document.createElement("a")).constructor !== HTMLUnknownElement I noticed several functional HTML elements (like "font") were not in the list, so might be nice to just trust the browser (not sure how you'd get the correct count per browser though).

<object> works, but I was surprised as well that the others don't. It was really hard for me to come up with many tags that are still allowed.
TheRealPomax 2y ago
Correctly: almost all of them were removed from the HTML spec many years ago (but not <object>, that's still a valid HTML5 element). But: invalid according to the spec doesn't mean it won't do something in a browser, browsers aren't pure spec implementations, they're applications used by humans to view content made by humans =)

If you want to see which ones you've missed, put this in the JS console: Els.filter((item) => {return !

Elsguessed.includes(item)}).map((item) => {console.log(`https://developer.mozilla.org/en-US/docs/Web/HTML/Element/${item}`)}) I got to 80 found / 34 remaining (plus, of course, various deprecated tags and some which I'm very surprised were not deprecated such as map). Of the remaining ones, I've used several in the past and would have been able to say what they do... stupid memory is bad at enumeration!

> in the JS console in the CodePen console, not in the browser's console. here's a shorter version. Els.filter(item => !Elsguessed.includes(item)).forEach(item => console.log(`https://developer.mozilla.org/en-US/docs/Web/HTML/Element/${item}`)) or new Set(Els).difference(new Set(Elsguessed))

Many people mention marquee and blink. Neither of those have ever been part of any HTML specification since the dawn of HTML. marquee was inserted into the current version of HTML for the sole purpose of marking it obsolete because so many people were using it (so I was told long ago).

Got around 82 by cheating a bit and looking at some old pages on my site.

I got to 42 tags, after hitting two tags that exist but were considered invalid by this game (tt, center) I gave up :)

I feel so stupid to left out h1-h6. Also completely forgot about the entire table related tags.
