You can namespace all CSS rules. It's annoying in CSS, but really easy in LESS and SASS.
e.g.
my-namespace {
.button {
color: red;
}
.another-button {
color: blue;
}
}
The namespace can be a custom element name, a class or an ID.
The problem with this approach is that you need to declare the namespace in DOM somehow, and depending on the project that can either be easy or rather difficult. I used this technique when I ported a stand-alone application with classes just like ".button" to be a single page in a larger application, and it worked fine.
Anyway, I do think that CSS should have a proper solution to modularization.
EDIT: Now that I could open the link (it didn't open for me previously), I now see that this approach doesn't solve the problem with the article, since it doesn't support nested namespaces. (Although a hacky solution would be a 'reset all rules' helper in the inner namespace).
- talmand 12y agoI have a project now, with multiple developers, that uses this system; we've never had any conflicts in our CSS and I seriously doubt we ever will. It's mostly component driven with the occasional global selector. As for your example not working with the approach, that's one of the problems as I see it with these solutions. The fancy, complicated approach apparently doesn't support one of the basics of CSS which would go a long way to fixing the problem as they see it.
- ttty 12y agoWhat if component A and component B need that button? You will comp-a,comp-b{.button{}}? Will you save in comp-a-and-comp-b.scss? What if you need in comp-c and comp-d? As you can see your button is not tight to that comp. I prefer to have a button class, for example in react that when instanced renders all the time the same. It boundles it's css within, just like this lib.
- nawitus 12y agoYou could use the namespace feature of Less for that: http://lesscss.org/features/#features-overview-feature-namespaces-and-accessors http://lesscss.org/features/#features-overview-feature-names... I haven't personally used it, though. Another solution would be have a "button.less" like this: comp-a, comp-b, comp-c { .button { } }
- talmand 12y agoThere's nothing stopping you from doing any of that with CSS today, especially if you use SASS or LESS.
- Offler 12y agoSASS and LESS are CSS DSLs, you are doing limited programming with CSS, at that stage you may as well do programming in a Turing complete language like JS and reduce the number of tools in your tool chain.
