It's not easy to build very good UI components. A global effort to try and find the best qualities of components would be a great opportunity to improve components everywhere.

Notes from discussions on 11.8, the part of EN 301 549 that is about authoring tools.

What does “built in accessibility” actually mean for browsers that support popover?

Are LLMs helpful tools to assist with making accessible front-end components? Let's find out.

Common questions I hear about web accesssibility with short, low on nuance answers.

When someone called out lack of accessibility, they got ableist responses. This post has a collection of those responses and an explanation of why they're problematic.

Design systems come with a lot of promises. While those promises can be realised, that's not a given. And there's a lot to be said about process and how it works on the inside. During Design Systems Week, we'll get a peak into of the work of some very interesting teams.

OpenAI, the company that makes ChatGPT, now offers a way for websites to opt out of its crawler. By default, it will just use web content as it sees fit. How rude!

When organisations force LLM-output on users instead of paying people to create their content, they don't center users.

I'm joining the CSS Working Group as an Invited Expert.

Popovers are in the top layer, how can we position them relative to invokers that are not?

Large Language Models (LLMs) and tools based on them (like ChatGPT) are a popular topic among technologists today. I struggle with the optimism I see from businesses, the haphazard deployment of these systems and the seemingly ever-expanding boundaries of what we are prepared to call “artificially intelligent”.

To improve accessibility of the web as it is today, I feel we dearly need accessibility guidance that is holistic, well tested and easy to use.

A bit meta: this post is about how I blog and what I wrote about in the last while.

A bit about designing min-content, max-content and auto, and how they can be used.

Recreating old posters, I figured there are at least two approaches to deciding how many grid tracks your component or page needs: one can make it visually perfect, the other is more flexible if content is bound to change.

It can be done by listening to focus on the document, with capturing turned on.

On lang, hreflang and BCP47.

With more people using tracking protection features, we should test our sites with content blockers.

Heading structures give screenreader users and others a table of contents for our sites. By being conscious of that, we can make better choices about heading levels and their contents.

Now that Grid Layout is seeing more adoption, it seems like a good time to remember that websites don’t need to look the same in all browsers.

By documenting a web design as a system of components, your website can be an instantiation of your design system.

What’s the difference?

I like WordPress plug-ins that do not insert their own CSS or JavaScript.

We can soon use ‘just’ CSS to describe our lay-outs. But, arguably, that leaves us with a naming problem.

I think for large websites and organisations, in addition to having a component system, it makes sense to have one agreed-upon, shared-between-projects grid system.

I think when designing apps that work offline, we should consider user intent and let users choose which content becomes available offline.

Web Components give developers lots of freedom, but also a big responsibility. In this post, I look at the kind of components we need.

Every time you add HTML to a page, think ‘what does this expose to the accessibility tree?’ My notes from Léonie Watson’s talk at Accessible Bristol.

Website slowness is optional, and I think that it can and should be avoided. The web is fast by default, let’s keep it fast.

To solve CSS problems, it is much more important to understand the spec and how browsers implemented it, than which abstraction to use.

Google’s algorithm for deciding wether sites are “mobile friendly” is great, but not perfect. In this article, I go into other things we could do to make sites more mobile friendly.
