Have you ever wanted to create more interesting shapes on the web, or flow text around the details of an image? Shape paths can be hard to code without a visual reference, but Firefox provides a shape editor to make it quick and clear.

“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…

Firefox 69 was the first to implement selector feature queries, but other browsers are following suit. I’ll show you how it works, and how to start using this new feature query right away.

Horizontal text overflow has always been difficult to manage on the web. The default visible overflow is designed to make sure content remains accessible no matter the size of a containing box, but it’s not our only option.

When we’re scrolling down a page, or through a gallery of images, snap-targets can help guide us from one section or image to the next. In the past, developers have used JavaScript to hijack scrolling, but now we can manage scroll alignment directly in CSS with only a few lines…

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.
