Heck of a year, eh? Like we do ever year, I’d like to give you a huge thanks for reading CSS-Tricks, and recap the year. More downs than ups, all told. Here at CSS-Tricks, it was more of a …

Eleventy is increasing in popularity because it allows us to create nice, simple websites, but also — because it’s so developer-friendly. We can build large-scale, complex projects with it, too. In this tutorial we’re going to demonstrate that expansive capability …

A font-display setting for slow connections
31.12.2020
Me, I really dislike FOUT. I like that it’s an option, because not displaying text quickly on the web is no good. I know font-display: swap; is popular because it’s good for performance, but that FOUT stuff pains me. Matt …

Cloudinary Tricks for Video
30.12.2020
Creating video is time consuming. A well-made 5-minute video can take hours to plan, record, and edit — and that’s before we start talking about making that video consistent with all the other videos on your site.
When we took …

The Rules of Margin Collapse
30.12.2020
Josh Comeau covers the concept of margin collapsing:
This idea might sound simple, but if you’ve been writing CSS for a while, you’ve almost certainly been surprised when margins either don’t collapse, or they collapse in weird and unexpected ways.

Design v18
29.12.2020
I redesigned the site! I can never think about the word redesign without also thinking about realigning, from Cameron Moll’s seminal article. I did not start from nothing. This design wasn’t a blank design canvas and empty code …

Automatic Social Share Images
29.12.2020
It’s a pretty low-effort thing to get a big fancy link preview on social media. Toss a handful of specific <meta> tags on a URL and you get a big image-title-description thing. Here’s Twitter’s version of an article on this …

Simulating Drop Shadows with the CSS Paint API
29.12.2020
Ask a hundred front-end developers, and most, if not all, of them will have used the box-shadow property in their careers. Shadows are enduringly popular, and can add an elegant, subtle effect if used properly. But shadows occupy a strange …

Accessible SVG Icons
28.12.2020
The answer to “What is the most accessible HTML for an SVG icon?” isn’t one-size-fits all, because what an icon needs to do on a website varies. I’m partial to Heather Migliorisi’s research on all this, but I can summarize.…

Create a Tag Cloud with some Simple CSS and even Simpler JavaScript
28.12.2020
I’ve always liked tag clouds. I like the UX of seeing what tags are most popular on a website by seeing the relative font size of the tags, popular tags being bigger. They seem to have fallen out of fashion, …

clipPath vs. mask
27.12.2020
These things are so similar, I find it hard to keep them straight. This is a nice little explanation from viewBox (what a cool name and URL, I hope they keep it up).
The big thing is that clipPath (the element in SVG, as well as clip-path in CSS) is vector and when it is applied, whatever you...
A Utility Class for Covering Elements
26.12.2020
Big ol’ same to Michelle Barker here:
Here’s something I find myself needing to do again and again in CSS: completely covering one element with another. It’s the same CSS every time: the first element (the one that needs to be covered) has position: relative applied to it....
Responsible, Conditional Loading
25.12.2020
Over on the Polyplane blog (there’s no byline but presumably it’s Kilian Valkhof), there is a great article, Creating websites with prefers-reduced-data, about the prefers-reduced-data media query. No browser support yet, but eventually you can use it in CSS to make choices that reduce...
Integrating TypeScript with Svelte
24.12.2020
Svelte is one of the newer JavaScript frameworks and it’s rapidly rising in popularity. It’s a template-based framework, but one which allows for arbitrary JavaScript inside the template bindings; it has a superb reactivity story that’s simple, flexible and effective; and as an ahead-of-time (AOT)...
A Calendar in Three Lines of CSS
24.12.2020
This article has no byline and is on a website that is even more weirdly specific than this one is, but I appreciate the trick here. A seven-column grid makes for a calendar layout pretty quick. You can let the days (grid items) fall onto it naturally, except kick the first day over to the correct...
Custom Styles in GitHub Readme Files
23.12.2020
Even though GitHub Readme files (typically ./readme.md) are Markdown, and although Markdown supports HTML, you can’t put <style> or <script> tags init. (Well, you can, they just get stripped.) So you can’t apply custom styles there. Or can you?
You can use SVG as...
Continuous Performance Analysis with Lighthouse CI and GitHub Actions

Lighthouse is a free and open-source tool for assessing your website’s performance, accessibility, progressive web app metrics, SEO, and more. The easiest way to use it is through the Chrome DevTools panel. Once you open the DevTools, you will see a “Lighthouse” tab. Clicking the “Generate report”...
