Cascade layers are a new CSS feature
that allows us to define
explicit contained layers of specificity,
so that we have full control over
which styles take priority in a project
without relying on specificity hacks or !important.
This guide is intended to help you fully understand
what cascade layers are for,
how and why you might choose to use them,
the current levels of support,
and the syntax.
I joined some other folks behind CSS-Tricks (maybe you’ve heard of it?) to face off in the much beloved don’t-call-it-jeopardy game show. Play along while you listen (or watch). It’s JS Danger time, y’all!

“What is one thing you learned about building websites this year?” I’ve always enjoyed the CSS art people create, but I’ve never ventured into it much myself. I’m familiar with many of the tricks involved, but still find it surprising every time: the way people are able to…
Since the inception of CSS in 1994, the cascade and inheritance have defined how we design on the web. Both are powerful features, but as authors we’ve had very little control over how they interact.

“What about building websites has you interested this year?” The role of ethics in our modern web space has been on my mind for the past few years and I suspect it will occupy my thoughts increasingly as I move forward. With each encounter of a questionable feature…
Sass recently launched a major new feature you might recognize from other languages: a module system. The new syntax will replace @import with @use and @forward – a big step forward for making Sass partials (one of the language’s most used features) more readable, performant, and safe. This article goes…
Inspired by Robin Rendle, I demonstrate some of my early experiments combining CSS Grids and custom properties to create dynamic layouts and data-visualizations.
Viewport units have been around for several years now, with near-perfect support in the major browsers, but I keep finding new and exciting ways to use them. I thought it would be fun to review the basics, and then round-up some of my favorite use-cases.
It feels like CSS Grid has been coming for a long time now, but it just now seems to be reaching a point where folks are talking more and more about it and that it’s becoming something we should learning.
No matter what acronym drives your selectors (BEM, OOCSS, SMACSS, ETC), loops can help keep your patterns more readable and maintainable, baking them directly into your code. We’ll take a look at what loops can do, and how to use them in the major CSS preprocessors.
