It’s been a few years since the Interop initiative was set in play. This has historically been one of the key elements in moving the web forward as it aims for a consistent web between browser vendors. In contrast to the “old days browser wars”, we as developers get streamlined features without having to check everything in every browser. The features of Interop 2025 are now known, features to be made stable across browsers by the end of the year. In this article, we’ll take a look at what we should get acquainted with in 2025.

The customizable select has entered Chrome 134, allowing us to style this form element to our hearts' content. I decided to write a series about this feature because there are so many cool things we can do with CSS these days to create some really unique and fun experiences. In this first article of the series, I want to talk a bit about the history, while also giving an in-depth guide on how you can start creating your first customizable select as a progressive enhancement, today.

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.

It’s not always the big features that make our everyday lives easier; sometimes, it’s those ease-of-life features that truly enhance our projects. In this article, I want to highlight two such features: @starting-style and transition-behavior — two properties that are absolutely welcome additions to your everyday work with CSS animations.

The year was 2018, and we were still trying to cope with IE11 and had to find some ways for certain effects. Things that we take for granted with CSS nowadays were not possible and one of the solutions to create awesome effects on the web was using SVG Filters. Fast forward to 2025, SVG filters are still awesome, but I use them less. In this article, I wanted to revisit them, with some easy-to-use effects we can use today.

Who publishes an article on the last day of the year? This guy! I felt like I should honor the tradition of at least recapping the past year by writing one final article in 2024. So this time, there will be no tutorials or hidden code gems. I already created my holiday CSS greeting card. This is just a little personal reflection and future plans for 2025.

Every year, I create a little demo right before the holidays as a CSS greeting card. This year is no different. To celebrate the end of the year and all those new amazing features that came into CSS, I decided to let myself go a little with new CSS techniques. A sort of recap of things I learned and put them in one little CodePen. This time, I’m combining scroll-driven animations, anchoring, and @property in CSS.

How can I animate from 0 to auto? I have a fixed width and want it to transition to the width set by its children. How do I do that? These CSS questions have been asked many times on platforms such as Stackoverflow, and I’ve certainly done some searching for those exact questions. I can’t count the number of max-width hacks or JavaScript solutions I’ve used to transition from 0 to auto. No more! I’m done, and for now, I’m going full progressive enhancement. In this article, I’d like to cover some of the benefits you get from adding the new interpolate-size property in your CSS Reset.

As a GDE, I recently traveled to the Isle of Man. It’s probably not the first place you would think of when talking about conferences, meetups, and developer communities in general. You’ll probably think about motor races in narrow streets and beautiful hills. This event was once again an eye-opener for me to realize we should probably try to do more for smaller community groups whether that is government sponsorships, or just doing that - maybe literally - extra mile as a speaker.
