Web Component for a Code Block


We'll get to that, but first, a long-winded introduction. I'm still not in a confident place knowing a good time to use native web components. The templating isn't particularly robust, so that doesn't draw me in. There is no state management, and I like having standard ways of handling that. If...

Moving from Vanilla JavaScript to a Reusable Vue Component


I recently wrote an article explaining how you can create a countdown timer using HTML, CSS and JavaScript. Now, let’s look at how we can make that a reusable component by porting it into Vue using basic features that the framework provides. Why do this...

“CSS4” Update


Since I first chimed in on the CSS4¹ thing, there's been tons of more discussion on it. I'm going to round up my favorite thoughts from others here. There is an overwhelming amount of talk about this, so I'm going to distill it here down as far as I can, hopefully making it easier to follow. Jen...

Creating a Details Element That Opens But Never Closes


The <details> and <summary> elements in HTML are useful for making content toggles for bits of text. By default, you see the <summary> element with a toggle triangle (▶︎) next to it. Click that to expand the rest of the text inside the <details> element. But...

While You Weren’t Looking, CSS Gradients Got Better


One thing that caught my eye on the list of features for Lea Verou's conic-gradient() polyfill was the last item: Supports double position syntax (two positions for the same color stop, as a shortcut for two consecutive color stops with the same color) Surprisingly, I recently discovered most...

Why JavaScript is Eating HTML


Web development is always changing. One trend in particular has become very popular lately, and it fundamentally goes against the conventional wisdom about how a web page should be made. It is exciting for some but frustrating for others, and the reasons for both are difficult to explain. A...

Building an Images Gallery using PixiJS and WebGL


Sometimes, we have to go a little further than HTML, CSS and JavaScript to create the UI we need, and instead use other resources, like SVG, WebGL, canvas and others. For example, the most amazing effects can be created with WebGL, because...

The Hooks of React Router


React Router 5 embraces the power of hooks and has introduced four different hooks to help with routing. You will find this article useful if you are looking for a quick primer on the new patterns of React Router. But before we look at hooks, we will start off with a new route rendering...

How to Fetch and Parse RSS Feeds in JavaScript


Say you have an RSS feed like this one. The goal is to request that RSS feed, parse it, and do something useful with the data in it. RSS is XML, and XML is arguably not as easy to work with than JSON. While a lot of APIs offer JSON responses, it's less typical for RSS, although it does exist. Let's...

Design Systems Blogathon


It was fun watching a bunch of back and forth blogging between a bunch of smart people quoting a bunch of smart people last week. If you missed it, you might wanna start at the end and work backward. I only have one tidbit to add. I don't do much with design systems as someone who works on pretty...

The Case of the Stolen Domain Names


Back in 2011, the domain name for this site, css-tricks.com, was stolen. "Domain Hijacking," they call it. It wasn't just this site, but around 12 others in the design and development space. To this day, none of us really know how it happened and who was behind it, although I believe all...

Is Having an RSS Feed Just Giving Content Away for Free?


I mean, kinda. I was just asked this question the other day so I'm answering here because blogging is cool. The point of an RSS feed is for people to read your content elsewhere (hence the last part of the acronym, Syndication, as in, broadcasting elsewhere). Probably an RSS reader. But RSS...

Guillermo’s 2019 in Review


Of all the tech-focused year-in-review posts I read, Guillermo Rauch's is my favorite. There is a lot in there, jumping from topics like modern architectures, high-fiving specific apps, and philosophical movements. I'll pick one quote about the rise of "deploy previews": A salient feature is...

Custom Styling Form Inputs With Modern CSS Features


It’s entirely possible to build custom checkboxes, radio buttons, and toggle switches these days, while staying semantic and accessible. We don’t even need a single line of JavaScript or extra HTML elements! It’s actually gotten easier lately than it has been in the past. Let’s take a look. Here’s...

Full-Width Elements By Using Edge-to-Edge Grid


If you have a limited-width container, say a centered column of text, "breaking out" of that to make a full-width element involves trickery. Perhaps the best trick is the one with left relative positioning and a negative left viewport-based margin. While it has it's caveats (e.g. requiring hidden...
