Oh my, usually when writing a series like this, people tend to leave the best for last, but in this case, it seems that the best is behind us. But as I am a completionist, this last part of the CSS Units series will be about absolute units, the units you mostly - absolutely - want to avoid. But can help in certain cases.

A large part of adding interactivity to your applications is through forms. Single Page Applications SPAs have not always handled this part the best. Let’s have a look at how we can use React.js Server Actions to handle your forms progressively enhanced.

In the third part of this series, we’ll look at length units based on the container. Yes, you heard that right, we can finally get some measurements based on a containing element and that just spells awesome in my book. Currently available in all evergreen browsers, these units open up a lot of opportunities to create some smart systems and once again, I will write this up packed with a bunch of demos and cool use cases.

In this second part of the series, let’s talk about units based on the viewport also known as "the viewport-percentage length units". A lot of developers know these, but they can create some unexpected behavior, especially in combination with scrollbars and mobile behavior. Based on some articles and videos I picked up on the web from time to time, I'd like to explain some of the common pitfalls when using viewport units.

As developers and designers, we make a plethora of design decisions while building a website. We try to cater to everybody, but that is an impossible task. So how can we listen to some of the preferences of our users?

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. Instead of writing a list of which units are available in CSS that you can easily find on MDN as well, I thought I’d give some examples of where they could come in handy. I will create a mini-series out of this and for the first part, let’s start off with relative length units based on font.

My personal experiences after completing the IAAP Certified Professional in Accessibility Core Competencies exam.

Before the relative color syntax you had to rely on CSS variables or even worse: JavaScript to modify the parameters of a color. Using the from keyword the browser can convert the originating color to different color spaces and change the color properties.

The most exciting feature of Angular 17 might be Deferrable Views. It makes it possible to lazy load specific Angular standalone components or show a placeholder as the component is loading. It seems like this feature should go well with Skeletons. Stay around to find out.

The Coven of Wisdom Eindhoven meetup on Nov. 16th, in partnership with AWS and the amazing Samuel Sopeju from AWS, was a total blast! The goal was simple: dive headfirst into the deep end of machine learning using Amazon SageMaker. And we did just that!

AI-powered speech synthesis is getting incredibly realistic. This opens up many possibilities to generate realistic audio based on the text you provide. Whilst relatively fast, the latency still isn’t low enough for “real-time synthesis”. Let’s optimise that!

How can I improve the way someone interacts with ChatGPT? How can I make it feel more natural than a dreadful “chatbot”? Can I create something cool? Those were some of the questions I asked myself recently while starting a two-day hackathon at iO. I’ll take you through what I build, how, and most importantly, why.
