The complexities of containment, overflow, and ‘propagation’
I spoke about Container Queries at both Smashing Conference (San Francisco) and CSS Day (Amsterdam) – where I recommended setting up a root container to replace most media queries. Since then, Temani Afif pointed out a few issues with that approach, and sent me down a rabbit hole of overlapping…
Learn how to leverage Web Platform Tests to ensure your polyfills are implementing upcoming browser features correctly, including how to generate a comprehensive report of failing/passing tests on each change.
OddBird sponsored Python Web Conference 2023 and sent me to attend. In this article I showcase my favorite talks and activities from this excellent online event, including a list of useful resources for web application security, introductions to new PaaS providers, and a comparison of the most popular Python web…

A web development podcast from LogRocket
I talk with Noel Minchow about how to style the intrinsic web, what that means, and how it’s compatible with responsive design.
And every ‘best practice’ comes with caveats
There’s a well-established ‘best practice’ that CSS authors (as well as linters and minifiers) should remove units from any 0 value. It’s a fine rule in most cases, but there are a few common situations where it will break your code.
Experimenting with the shared element transitions API
There’s a new web API proposal for transitioning shared-elements across pages. It’s great for making smooth page transitions, but what if we apply it to individual elements with changing styles on a single page?
Cascade layers are an exciting new addition to the CSS specification. A newly released polyfill now provides even greater browser support for the feature.
100% test coverage is a contentious metric! In this piece, Olu explores the impact of pursuing it.
