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 …

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. …

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 …

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 However, just recently, I had a client reject one of my extensions as I received feedback that my extension was “outdated”.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 …

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 …

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 …

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. See ::scoobydoo in there? That’s totally invalid. A forgiving …

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 …

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 …

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 …

We’ve started making a tradition of rounding up the latest front-end research at the end of each year. We did it in 2020 and again in 2021. Reports are released throughout the year by a bunch of different companies and organizations researching everything from web design trends to developer skills to popular coding languages and …

CSS Nesting is making the rounds yet again. Remember earlier this year when Adam and Miriam put three syntax options up for a vote? Those results were tallied and it wasn’t even even close. Now there’s another chance to speak into the future of nesting, this time over at the WebKit blog. The results from …

Being able to quickly spin up a WordPress instance has been the strength of WordPress ever since its famous “five-minute install”. Upload a few files, configure a few settings, and you’re off. The friction of uploading files has gotten a lot easier, thanks to plenty of “one-click” install options many hosts offer (including DigitalOcean and …

In this series, we’ve been making image sliders with nothing but HTML and CSS. The idea is that we can use the same markup but different CSS to get wildly different results, no matter how many images we toss in. We started with a circular slider that rotates infinitely, sort of like a fidget spinner …

The CSS Working Group gave that a thumbs-up a couple weeks ago. The super-duper conceptual proposal being that we can animate or transition from, say, display: block to display: none. It’s a bit of a brain-twister to reason about because setting display: none on an element cancels animations. And adding it restarts animations. Per the …

Every so often, I find that the links I save to read later fall into natural groups or patterns that reveal common threads of interest. The past couple of weeks have produced a lot of thoughts about ChatGPT, an AI-powered interface that responds to requests in a chat-like exchange. Sorta like a “Hey Siri” request, …

Suzy Naschansky from the HTMHell Advent Calendar: See that aria-labelledby attribute? It chains two IDs from the markup, one for the heading (#article1-heading) and one for the link (#article1-read-more). What happens there is a screenreader will replace the existing semantic label between the link tags and use the content from both elements and announce them …

We’ve got ourselves a real holiday treat! Join host Alex Trost from the Frontend Horse community for the Holiday Snowtacular 2022 this Friday, December 16. There’s a lineup of 12 awesome speakers — including Chris Coyier, Cassidy Williams, Kevin Powell, and Angie Jones — each discussing various front-end and web dev topics. It’s like the …

CSS Container Queries are still gaining traction and many of us are getting our hands wet with them, even if it’s for little experiments or whatnot. They’ve got great, but not quite full, browser support — enough to justify using them in some projects, but maybe not to the extent where we might be tempted …

Sara Soueidan with everything you need, from what screen reading options are out there all the way to setting up virtual machines for them, installing them, and confguring keyboard options. It’s truly a one-stop reference that pulls together disparate tips for getting the most out of your screen reading accessibility testing. Thanks, Sara, for putting …

We’ve accomplished a bunch of stuff in this series! We created a custom WordPress block that fetches data from an external API and renders it on the front end. Then we took that work and extended it so the data also renders directly in the WordPress block editor. After that, we created a settings UI …

In the last article, we made a pretty cool little slider (or “carousel” if that’s what you prefer) that rotates in a circular direction. This time we are going to make one that flips through a stack of Polaroid images.

How often to do you reach for the CSS background-size property? If you’re like me — and probably lots of other front-end folks — then it’s usually when you background-size: cover an image to fill the space of an entire element. Well, I was presented with an interesting challenge that required more advanced background sizing: …

The CSS box-shadow and outline properties gained theme.json support in WordPress 6.1. Let’s look at a few examples of how it works in real themes, and what options we have to apply these styles to WordPress blocks and elements.

Nothing but ear-to-ear smiles as I was watching this video from @quayjn on YouTube. (No actual name in the byline, though I think it’s Brian Katz if my paper trail is correct). The best is this Pen you can use to sing along… The little song Una did for memorizing for JavaScript’s map(), filter(), and …

For years, a small pedantry war has been raging in our address bars. In one corner are brands like Google, Instagram, and Facebook. This group has chosen to redirect example.com to www.example.com. In the opposite corner: GitHub, DuckDuckGo, and Discord. This group has chosen to do the reverse and redirect www.example.com to example.com. Does “WWW” belong in a URL? Some developers …

Image sliders (also called carousels) are everywhere. There are a lot of CSS tricks to create the common slider where the images slide from left to right (or the opposite). It’s the same deal with the many JavaScript libraries out there that create fancy sliders with complex animations. We are not going to do any …

I wrote up some early thoughts on container style queries a little while back. It’s still early days. They’re already defined in the CSS Containment Module Level 1 specification (currently in Editor’s Draft status) but there’s still a couple of outstanding discussions taking place. The basic idea is that we can define a container and …

One of the main goals of the WordPress Site Editor (and, yes, that is now the “official” name) is to move basic block styling from CSS to structured JSON. JSON files are machine-readable, which makes it consumable by the JavaScript-based Site Editor for configuring a theme’s global styles directly in WordPress. It’s not all the …

I’m a sucker for anything about front-end job titles. Anselm Hannemann: CSS evolved and we’re beyond the point where everyone can just do it as a side interest. We all can learn it and build amazing stuff with it, but using it wisely and correctly in a large-scale context isn’t an easy job anymore. It …
