In this first part we will look at how natural language AI can offer developers a lot of benefits, from helping them write code to writing this blog post. Here, we will introduce you to two of the most popular natural language AI tools, OpenAI GPT-3 and GitHub Copilot, and discuss some of the best use cases for each.

The Shared Element Transitions API allows creating page transitions using a browser API that can provide users with a better visual connection between page-a and page-b by transitioning shared elements on both pages.

Every day a new JavaScript library is born, every week a new framework arrives and every month a front-end developer needs to rewrite a date picker 😢 LIT is a modern library for creating component libraries, design systems but also sites and apps. LIT components are web components and as such work anywhere you use HTML.

Why lit is 🔥

Container queries enables encapsulation of adaptive styling based on the size, style or state of a parent element. This allows responsive component-based architectures, like design systems and component libraries, to provide the most optimal responsive styling within a component itself.

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.

Going beyond pixels and (r)ems in CSS - Container query length units

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?

Your user doesn’t _prefer_ your design

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.

If you love CSS, you’ve probably heard of custom properties (a.k.a. CSS variables) before. Still, a lot of people seem to use them as constants for their CSS. In this article, I will try to give you some more insights on how you can use these custom properties to create some smart systems or even use them as booleans in CSS and create easy progressive enhancements.

Traditionally, developers have used build tools like Webpack or Rollup to bundle and optimize their code for production. These build processes can be time-consuming to set up and make development more complicated. With native JavaScript modules now widely supported in modern web browsers, there is a need to map JavaScript packages to their source files.

Import maps in JavaScript

We have seen how the industry has continuously raised the level of abstraction to allow developers to spend more time delivering functionality and less time writing low-level infrastructure. Even though JavaScript is the most versatile programming language on the planet, we still have a long way to go.

Cross-platform software development is hard. Each platform has its specific implementation of an API and you end up with separate apps for each platform. Multiple frameworks try to fix this issue by creating an abstract between the platform and the application. Browser vendors are doing the same and it's called Project Fugu.

In the previous part of this article, I tried to tickle your brain a bit to unleash your curiosity and drive your determination to try some new CSS features today. That's exactly what I'll be doing in this part, writing some new stuff today so you can slowly polish new CSS skills very sneaky and hidden in the code, like a ninja.

Why you should be using new CSS features today - part 2

Unless you have no affinity with CSS at all or have been living under a rock for the last year, you should have noticed that new CSS features are skyrocketing like never before. Although this is a good thing, it might get frustrating to get a grasp on all these new playthings because every time you add something new in your styling toolbox, the next best thing is just around the corner.

Ever since the introduction of Bun there are three runtimes to choose from when wanting to develop and run a JavaScript server. Node was the one that started it all and most applications are designed to run on that, but how would those applications fare running on the other runtimes, are they really a drop-in replacement?
