The display property has been in CSS from the beginning, handling everything from block and inline boxes to list-items and full layout systems like flexbox or grid. Now the display syntax is getting an upgrade to match it’s multiple uses.

I drop by the show to talk about Sass in 2019, design tokens, OddBird, unused CSS, new CSS properties, and Dave & Chris’ explanation of revert.

There are a number of property & value combinations that can lead to CSS being inactive, and now Firefox will tell you why. Open the developer tools, and look for the greyed-out property with an info-box on hover.

For years, we’ve struggled to build resilient layouts on the web, but CSS Grid promises to change all that – and you can start using it now, with only a few properties and basic concepts.

It’s a common pattern to align form labels and inputs in grid-like layout. I’ll show you how to do it quickly using CSS subgrid, with several quick fallbacks.

Card layouts are popular on the web, rows and columns of boxes with similar content. CSS grids can help align those cards, but it’s still be hard to line-up content inside the cards – headers and footers that might need more or less room.

I’ve often used initial and unset in my CSS – global keywords that can be applied to any property. The difference is small, but important: unset allows inheritance, while initial does not. But then Firefox implemented revert and I was confused – how is this one different from the others?

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…

CSS is the design language of the web – one of three core web languages – but it also seems to be the most contentious and often perplexing. It’s too easy and too hard, too fragile and too resilient. Love it or hate it, CSS is weird: not quite markup…

Dart Sass (the primary Sass implementation) released version 1.23.0 last night with a major new feature: modules. This is a common feature in many languages – but for those of us who primarily write CSS, it can be a big mental shift. Let’s take a look at the basics.

Over the summer, we’ve been working with Mozilla to help create a new resource for web professionals like us – with a mix of videos, articles, demos, and open source tools. Today, we’re excited to launch the video channel!

When you create lists in HTML, browsers add bullet-points or numbers we call list markers. Now CSS gives us the tools to style those list markers, and even create our own!

Hooks are the new hotness in building web applications with React. In this article for BitSrc, Erica separates fact from hyperbole to examine why OddBird has embraced the new Hooks API to deliver a better product to clients, and how we’ve benefited from having simple, consistent patterns to manage state…

We start by talking about design systems and design tooling – how they differ, and the problems they solve.

Pushing past the “variable” metaphor, CSS Custom Properties can provide new ways to balance context and isolation in our patterns and components.
