OddBird’s color tool not only checks contrast ratios, but supports the new CSS color formats and spaces.

I talk with Noel Minchow about the philosophy and evolution of web design. We explore CSS origins, the cascade, accessibility, and how the balance between user control and brand expression defines the spirit of the web.

Miriam Suzanne and Stacy Kvernmo answer questions from listeners about CSS – what the next big evolution for CSS may be, how to make a site more accessible, whether float is still useful, and what’s on their CSS wish list.

We have been busy updating the Popover and CSS Anchor Positioning Polyfills, but there is still more we can do with your help.

Many people asked about using it to set the ‘logical’ inline-size and block-size properties instead. But ‘logical shorthands’ have been stalled in the working group for years. Can we…

CSS anchor positioning simplifies popovers and dropdowns, and also unlocks new creative possibilities. James joined Jason to teach and explore anchor positioning in live code.

Kevin and I chat about getting involved with the development of the CSS language, from following along to opening issues, or even joining the CSS Working Group.
