I’m pleased to shine a light on the fact that the CSS grid-template-rows and grid-template-columns properties are now animatable in all major web browsers! Well, CSS Grid has technically supported animations for a long time, as it’s baked right into the CSS Grid Layout Module Level 1 spec. But animating these grid properties only recently gained supported by all three major browsers. Shall we take a look at a few examples to get the creative juices flowing? Tabl..

SvelteKit is the latest of what I’d call next-gen application frameworks. It, of course, scaffolds an application for you, with the file-based routing, deployment, and server-side rendering that Next has done forever. But SvelteKit also supports nested layouts, server mutations that sync up the data on your page, and some other niceties we’ll get into. This post is meant to be a high-level introduction to hopefully build some excitement for anyone who’s never used Sv..

The :has() pseudo-class is, hands-down, my favorite new CSS feature. I know it is for many of you as well, at least those of you who took the State of CSS survey. The ability to write selectors upside down gives us more superpowers I’d never thought possible. I say “more superpowers” because there have already been a ton of really amazing clever ideas published by a bunch of super smart people, like: Using :has() as a CSS Parent Selector and much more by Jen Simm..

While I am not a regular Chrome extension programmer, I have certainly coded enough extensions and have a wide enough web development portfolio to know my way around the task. However, just recently, I had a client reject one of my extensions as I received feedback that my extension was “outdated”. As I was scrambling to figure out what was wrong, I swept my embarrassment under the carpet and immediately began my deep dive back into the world of Chrome Extensions. Unfo..

If you’ve ever worked on sites with lots of long-form text — especially CMS sites where people can enter screeds of text in a WYSIWYG editor — you’ve likely had to write CSS to manage the vertical spacing between different typographic elements, like headings, paragraphs, lists and so on. It’s surprisingly tricky to get this right. And it’s one reason why things like the Tailwind Typography plugin and Stack Overflow’s Prose exist — although these handle much..

Someone recently asked me how I approach debugging inline SVGs. Because it is part of the DOM, we can inspect any inline SVG in any browser DevTools. And because of that, we have the ability to scope things out and uncover any potential issues or opportunities to optimize the SVG. But sometimes, we can’t even see our SVGs at all. In those cases, there are six specific things that I look for when I’m debugging. 1. The viewBox values The viewBox is a common point..

A little thing happened on the way to publishing the CSS :has() selector to the ol’ Almanac. I had originally described :has() as a “forgiving” selector, the idea being that anything in its argument is evaluated, even if one or more of the items is invalid. /* Example: Do not use! */ article:has(h2, ul, ::-scoobydoo) { } See ::scoobydoo in there? That’s totally invalid. A forgiving selector list ignores that bogus selector and proceeds to evaluate the rest of th..

The good ol’ <table> tag is the most semantic HTML for showing tabular data. But I find it very hard to control how the table is presented, particularly column widths in a dynamic environment where you might not know how much content is going into each table cell. In some cases, one column is super wide while others are scrunched up. Other times, we get equal widths, but at the expense of a column that contains more content and needs more space. But I found a CSS t..

A little while back, Ganesh Dahal penned a post here on CSS-Tricks responding to a tweet that asked about adding CSS box shadows on WordPress blocks and elements. There’s a lot of great stuff in there that leverages new features that shipped in WordPress 6.1 that provide controls for applying shadows to things directly in the Block Editor and Site Editor UI. Ganesh touched briefly on button elements in that post. I want to pick that up and go deeper into approaches for s..

You know, this is the time of year where Chris normally publishes a big ol’ reflection of the past year. The first one was published in 2007, the same year CSS-Tricks began, and it continued all the way through 2021 without missing a beat. Having been a CSS-Tricks reader myself all those years, I’d hate to see that change. So, here we are! 2022 was sure a heckuva year as far as transition goes. At this time last year, we were looking ahead at some goals for the upcomin..
