Scroll-driven animations are one of my favourite things in CSS. But if you have ever tried to build an interactive story with them, you probably noticed that scrubbing is not always what you want. There are cases where you just want the scroll position to tell an animation when to start, and then let it play smoothly with its own timing. Now that the W3C has specced CSS Animation Triggers and it is a candidate for Interop 2027, we might be getting this sooner than I thought. I built a few demos to try it out, and I want to share what I learned.

Modern Web Guidance is a set of skills from the Chrome and Edge teams that feeds expert-written platform guidance straight into your coding agent, with Baseline compatibility data baked in. It's good, but it also has no idea what your design system looks like. This post is about how it works, how I pair it with my own token skills, why fallbacks and polyfills matter, and the honest bits about data it keeps, the licence, and that whole you're just doing Google work for free argument.

Between all the fancy features such as container style queries, contrast-color(), gap decorations, corners-shape... there are some features that became baseline available and we forgot about them. They are those little things that make life a bit easier. I wanted to search for the kinds of features that I don’t need on a regular basis, but am happy to know are available. This article is all about the CSS Custom Highlight API, text-indents and math.

About half a year ago I wrote about the idea to have multi-handle range sliders as a native HTML element. I asked for feedback, and the community delivered. The proposal has moved forward since then, but it needs more voices to get browser vendors on board. Here's what happened, what changed, and what you can do. This article shows some of the survey results, and is a big call for help.

A few weeks ago, I didn't think I'd start the year with another demo on customizable select. To be honest, I was hoping to let it go for a little while. But there is an update on the rise that needs to be talked about: The multiple select. This little attribute could change a lot of things in making multiple selections; it could turn a series of checkboxes into one element, and it could improve accessibility. This is still in development, but we can take a peek in Chrome Canary.

We need to talk about multi-handle range sliders… Really, we do. They’re one of those UI elements we see on a variety of web shops indicating price ranges; we see them for selecting time-slots; we see them for filtering between a variety of lenght units. Creating these experiences is more often inaccessible than just working, and even when I found the so-called perfect library, I’d still run into limitations for styling and expanding upon it. I thought that I should do something about this. I might be way over my head, and that is why I need your help...

A little while ago, in Chrome 133, a feature called popover=”hint” landed in the browser. This feature paved the way to something bigger, more specifically, popovers being triggered on hover/focus. This comes with a new attribute “interestfor” and some CSS properties to change the delay speed when showing popovers using that method. There still isn’t much definitive on how this should behave on devices without hover capabilities, and that’s what this article is all about. I want to make sure the content of these popovers is accessible on touch devices.

In this (long) part of the customizable select series, it’s all about gamification. In this article, I’d like to highlight one of my demos, where I aimed to recreate a piece of UI found in the Monster Hunter games. To re-create this behavior, I had to think in terms of keyboard navigation first. This demo requires quite a lot of CSS, as well as some scripting, and in the end, I do want to highlight some accessibility concerns. This is an experiment on how far we can take it when styling select elements.

It’s Valentine's Day! As usual, I want to write about something I love, and this time it’s still highly experimental but something I am extremely excited about. Something new is on the horizon named CSS scroll-markers and it allows you to create a fully functional slider without the need of any JavaScript. Don’t believe me? Let’s take a look, shall we? Here is my first impression of creating a carousel with only CSS and some accessibility concerns as well.

Have you ever wondered what happened after CSS3? The W3C CSS-Next community group is actively searching for better approaches for how we describe the evolution of CSS over time and identify feature sets as effectively as we did with CSS3 way back in 2009 — and you can help.

Another year, another CSS Day. I’m always happy to return to Amsterdam for this occasion, It’s one of the things I look forward to every year. So naturally, I’m happy that iO still allowed me to go there with my training budget, and the least I could do, is write a summary of this event on the tech_hub.

It’s easy to get lost in a sea of CSS frameworks and libraries, each promising easier styling and smoother layouts. But amidst this abundance, the modern CSS features we have today offer simpler and more flexible approaches without the added dependencies or abstractions. In this article, I demonstrate four CSS utility classes (plus a bonus) using techniques that allow them to be used practically anywhere you need a particular layout — be it Grid or Flexbox — with configurable options.

There are a lot of CSS units available at the moment and we mostly still rely on pixels and (r)ems for our sizing and fonts. I say it’s time to do a little freshening up. In this mini-series I will be going around all the current length units in CSS with practical examples.

From layers and specificity to nesting, from HD color to (scroll) animations. If there is one thing that makes me keep using Chrome as my default browser while developing, it has to be the DevTools and the information we can find about them. As we’re slowly entering the last part of the year, I thought a cool roundup of new CSS debugging tools would be a great article. Let’s dive into it.

A lot of developers use Chrome as their main browser and I'm one of them. There are a few tricks in Chrome DevTools that don't seem to get enough attention. So for this article, I wanted to highlight some of the features that I love and actually use in DevTools, that some of you might not know about.

If it pops, it belongs in HTML and CSS! Lately, I had a lot of fun playing around with this upcoming feature. The first version is being developed and it's starting to look pretty good. It's time to handle our basic popovers without the explicit need of JavaScript.

Design should never be a trade-off when it comes to creating an accessible web. There are many features coming to the web that will make creating contrast a lot easier. But even though CSS functions such as color-contrast() are only available in Safari behind a flag, we can already do a lot to create contrast in an easy way by using custom properties.

Scroll snapping is hip and while we all have styled numerous sorts of tab panes and scroll boxes, I had an idea of combining them. What started out as a simple “scroll snapping experiment” turned out to be an accessibility study. How should scroll snapping tabs behave when using keys? By reading some best practices, I believe I found an elegant solution.

As we're entering the last stages of 2021, I think it's time to add a little wishlist for the future of the web. Since accessibility is getting more (deserved) notice. I thought that this year might be a good time for an HTML wishlist.
