This detailed proposal from Miriam for scoping CSS is well worth reading—it makes a lot of sense to me.
This is supposed to be a defence of utility classes …but it’s actually a great explanation of why classes in general are a great mechanism for styling.
I don’t think anyone has ever seriously suggested using inline styles—the actual disagreement is about how ludicrously rigid and wasteful the class names dictated by something like Tailwind are. When people criticise those classes they aren’t advocating for inline styles—they’re advocating for better class names and making more use of the power of the class selector in CSS, not less.
Anyway, if you removed every instance of the word “utility” from this article, it would still work.
This would be such a great addition to CSS—a parent/ancestor selector!
With the combined might of
calc(), CSS has become a powerful language for specifying rules to account for all kinds of situations.
A handy tool for getting an overview of your site’s CSS:
CSS Stats provides analytics and visualizations for your stylesheets. This information can be used to improve consistency in your design, track performance of your app, and diagnose complex areas before it snowballs out of control.
An excellent and clear explanation of specificity in CSS.
I can see this coming in very handy at Codebar—pop any CSS selector in here and get a plain English explanation of what it’s doing.
This is a wonderful interactive explanation of the way CSS hierarchy works—beautiful!
Everyone wants it, but it sure seems like no one is actively working on it.
For fun, here’s some made-up syntax (which Jeremy has dubbed ‘selector queries’)…
Well, the clever CSS techniques just keep on comin’ from Trys—I’m learning so much from him!
This is a great explanation of the difference between the
:lang CSS selectors. I wouldn’t even have thought’ve the differences so this is really valuable to me.
Rachel gives us the run-down on what’s coming soon to Cascading Style Sheets near you, including an aspect-ratio unit and a
matches selector (as originally proposed by Lea).
The fascinating results of Brad’s survey.
Personally, I’m not a fan of nesting. I feel it obfuscates more than helps. And it makes searching for a specific selector tricky.
That said, Danielle feels quite strongly that nesting is the way to go, so on Clearleft projects, that’s how we write Sass + BEM.
A really deep dive into the
lang attribute, and the
:lang() pseudo-class (hitherto unknown to me). This is all proving really useful for a little side project I’m working on.
A deep dive into the
:focus pseudo-class and why it’s important.
Rebuttals to the most oft-asked requests for browsers to change the way they handle CSS.

A really interesting proposal from Lea that would allow CSS authors to make full use of selectors but without increasing specificity. Great thoughts in the comments too.
Following on from Ire’s post about linting HTML with CSS, here’s an older post from Ebay about how being specific with your CSS selectors can help avoid inaccessible markup getting into production.
