When managing css in large projects, specificity is your worst enemy. ID are not styled, if there are any. If your worried about being semantic for the header and footer, use the html5 header and footer tags.

> When managing css in large projects, specificity is your worst enemy I couldn't disagree more. The more specific you are the less side affects you'll encounter in the rest of your project. When a project gets incredibly large if your styles are NOT specific you're going to run into a lot of unintended consequences. This doesn't mean I encourage using IDs all over the place; they should only be used when there can be a single version of that element on the page. But being specific also means using the cascade (e.g. html > body > div.mydiv versus just .mydiv).

When a project gets incredibly large if your styles are NOT specific you're going to run into a lot of unintended consequences. You can handle 99% of use cases for specificity just nesting classes. Using IDs to settle specificity is the same as bringing an ICBM to a Nerf gun fight. When I was doing front-end development, I spent more time fighting back against overly specific CSS, thanks to IDs (and fellow developers who just sprinkled `important!` on everything until it worked), than struggling because I couldn't get specific enough without IDs.

    > You can handle 99% of use cases for specificity just nesting classes. Nesting classes can get really messy and I'm not sure that really makes sense to do in "99% of use cases" if the goal is to make something specific. Mixing classes allows you to apply multiple styles onto a single element which can be really handy but using that as the way to target a specific, single element means you can't re-use some of those classes in the same way otherwise you run the risk of targeting more than one element in the same way. Specificity should usually be handled through the cascade and / or IDs; that's what they were meant to do. Classes provide buckets of styles as do IDs and both can be used in the same way with IDs targeting only a single element and not a compose-able one. Ultimately you can specifically target in CSS a variety of ways. Outright saying one way is just wrong or "[an] ICBM" kinda ignores the use cases of the various ways to do it to attempt to force a single answer where I do not think a single answer is satisfactory.

  I find the opposite is generally the case. I've maintained many projects which were highly specific and therefore ridged to enhancing. I try to reuse some style to only find it doesn't work when placed somewhere else in the HTML. Having too generic styles is also a problem though. E.g. styling a label element on the assumption it's in a form can be frustrating. It's all about the right balance and styling specifcally what you mean, not the specific structure of the HTML.

  When running a large project, there is never just a single version of a ui element. For example, using media queries, different resolutions, zoom, and print. Or if write your css in oocss with separation of concerns. Being less specific allows your css to be more manageable to change in many different situations. In complicated layouts, cascades are very non-friendly. Styling elements directly also has very high specificity.

    > When running a large project, there is never just a single version of a ui element. For example, using media queries, different resolutions, zoom, and print. Not sure why you'd make such an absolute claim. When you say single version are you saying single html element or single CSS definition? If the former then I disagree (headers, footers, main containers of content, etc), if the latter then I don't understand how this would be the case. In HTML IDs are limited to one specific element but you can refer to it as many ways as you want in CSS which means you can use different media questions, handle resolutions, print, etc. So I'm not really sure I understand your point. > Being less specific allows your css to be more manageable to change in many different situations. In complicated layouts, cascades are very non-friendly. I've worked in a lot of really large projects and I'm not sure how little to no specificity could be more manageable due to side-effects. Ultimately you're going to need a mixture of specific and non-specific styling so arguing whether you should be more or less doesn't really make sense to me; just use the right level of specificity for the job at hand. If you have a page with specialized content you might want to be more specific there to not mess up another page. If you have a lot of re-usable components you probably want less.
