Web Development + Follow

Simon Goellner (@simeydotme)’s collection of Holographic Trading Cards have captured our attention. Under the hood there is a suite of filter(), background-blend-mode(), mix-blend-mode(), and clip-path() combinations that have been painstakingly tweaked to reach the desired effect. I ended up using a little img { visibility: hidden; } in DevTools to get a better sense of …

The CSS :has() pseudo class is rolling out in many browsers with Chrome and Safari already fully supporting it. It’s often referred to it as “the parent selector” — as in, we can select style a parent element from a child selector — but there is so much more that :has() can help us solve. …

As front-end developers, we’ve wished for a lot of things over the years — ways to center things in CSS, encapsulate styles, set an element’s aspect ratio, get finer-grained control over our colors, select an element based on its children’s properties, manage layers of specificity, allow elements to respond to the width of their parents… …

Welcome to Part 2 of this three-part series! We are still decorating images without any extra elements and pseudo-elements. I hope you already took the time to digest Part 1 because we will continue working with a lot of gradients to create awesome visual effects. We are also going to introduce the CSS mask property …

I love it when there’s a sense of synergy in the blogosphere. First, I caught Nick Heer’s coverage of Meta ending support for Instant Articles, its proprietary format for stripped-down performant news articles. He also compares it to the similar demise of AMP, Google’s answer to Instant Articles. Then I came across a new one …

Before I career jumped into development, I did a bunch of motion graphics work in After Effects. But even with that background, I still found animating on the web pretty baffling. Video graphics are designed within a specific ratio and then exported out. Done! But there aren’t any “export settings” on the web. We just …

When you put something — say a regular sheet of paper — in a manilla folder, a part of that thing might peek out of the folder a little bit. The same sort of thing with a wallet and credit cards. The cards poke out just a smidge so you can get a quick glance …

By way of a post by Manuel Matuzović which is by way of a demo by Temani Afif. You’d be doing yourself a favor to read Manuel’s breakdown of all what’s happening here, but it basically works out to the equivalent of this longer syntax:

Besides being elegant, Bezier curves have nice mathematical properties due to their definition and construction. No wonder they are widely used in so many areas! Now, how about using Bezier curves as motion paths with CSS?

Well, hey, welcome back to Behind the CSScenes! These posts are like little check-ins we’re doing each month to give you a peek behind what we’re doing here at CSS-Tricks, as well as a chance for us to pause and celebrate a few things. Last month, we shared a small taste of a redesign for …

As the title says, we are going to decorate images! There’s a bunch of other articles out there that talk about this, but what we’re covering here is quite a bit different because it’s more of a challenge. The challenge? Decorate an image using only the <img> tag and nothing more. That right, no extra …

An Event Apart 2022 Denver wrapped up yesterday. And while I was unable to make it to all three days this time, I did catch yesterday’s action — and it was awesome. I’m not very social or outgoing, but this was the first conference I’ve been to in at least a couple of years, and …

Oftentimes in the past, I needed to figure out how to add styles to all elements inside the container but not the hovered one. This effect requires selecting the siblings of a hovered element. I used to apply JavaScript for this, adding or removing the class that defined the proper CSS rules on mouseenter and …

We’re still in suuuuuper early days with container queries. Too early for broad browser support, but Chromium already supports it, Safari started supporting it in version 16, and Firefox is presumably not far behind. Most early days conversations revolving around container queries usually compare the syntax to media queries.

There’ve been some new tutorials popping here on CSS-Tricks for working with WordPress blocks. One of them is an introduction to WordPress block development and it’s a good place to learn what blocks are and to register them in WordPress for use in pages and posts. While the block basics are nicely covered in that …

Fluid typography is a fancy way of “describing font properties, such as size or line height, that scale fluidly according to the size of the viewport”. It’s also known by other names, like responsive typography, flexible type, fluid type, viewport sized typography, fluid typography, and even responsive display text. Here is an example of fluid …

Spammers are a huge deal nowadays. If you want to share your contact information without getting overwhelmed by spam email you need a solution. I run into this problem a few months ago. While I was researching how to solve it, I found different interesting solutions. Only one of them was perfect for my needs. …

In my previous post we looked at Shoelace, which is a component library with a full suite of UX components that are beautiful, accessible, and — perhaps unexpectedly — built with Web Components. This means they can be used with any JavaScript framework. While React’s Web Component interoperability is, at present, less than ideal, there …

The State of CSS survey recently opened up. Last year, the survey confirmed everyone’s assumptions that TailwindCSS is super popular and CSS variables are mainstream. It also codified what many of us want from CSS, from Container Queries to a parent selector. (Spoiler alert, we now have both of ’em.) While I wouldn’t say the …

This is a post about Shoelace, a component library by Cory LaViska, but with a twist. It defines all your standard UX components: tabs, modals, accordions, auto-completes, and much, much more. They look beautiful out of the box, are accessible, and fully customizable. But rather than creating these components in React, or Solid, or Svelte, …

Let’s acknowledge that developing for WordPress is weird right now. Whether you’re new to WordPress or have worked with it for eons, the introduction of “Full-Site Editing” (FSE) features, including the Block Editor (WordPress 5.0) and the Site Editor (WordPress 5.9), have upended the traditional way we build WordPress themes and plugins. Even though it’s …

So you want an auto-playing looping video without sound? In popular vernacular this is the very meaning of the word GIF. The word has stuck around but the image format itself is ancient and obsolete. Twitter, for example, has a “GIF” button that actually inserts a <video> element with an MP4 file into your tweet …

Did you know that DOM elements with IDs are accessible in JavaScript as global variables? It’s one of those things that’s been around, like, forever but I’m really digging into it for the first time. If this is the first time you’re hearing about it, brace yourself! We can see it in action simply by …

The wave is probably one of the most difficult shapes to make in CSS. We always try to approximate it with properties like border-radius and lots of magic numbers until we get something that feels kinda close. And that’s before we even get into wavy patterns, which are more difficult. “SVG it!” you might say, …

If we browse the WordPress theme directory, a majority of themes showcase cover images. It is a feature in popular demand. The cover page trend is true even in the block theme directory screenshots as well. Let’s consider the following example from Twenty Twenty (a classic theme) which includes a cover template that can be used to …

The video of Chris Coyier’s talk at CascadiaJS 2022 is now available. It’s his first in-person talk in more than two years, so it’s great to see our good friend back on stage slinging gems on what makes the web good these days. Container Queries! WAAPI! Scroll Timelines! offset-path! FLIP! Variable fonts! Fluid type! We …

SVG is the best format for icons on a website, there is no doubt about that. It allows you to have sharp icons no matter the screen pixel density, you can change the styles of the SVG on hover and you can even animate the icons with CSS or JavaScript. There are many ways to …

The latest spec: A style rule is a qualified rule that associates a selector list with a list of property declarations and possibly a list of nested rules. They are also called rule sets in CSS2. Louis Lazaris: As the above quote from W3C indicates, it seems like the W3C considers “rule set” to be a bit of an outdated term, preferring the term …

On one hand, creating simple checkered backgrounds with CSS is easy. On the other hand, though, unless we are one of the CSS-gradient-ninjas, we are kind of stuck with basic patterns. At least that’s what I thought while staring at the checkered background on my screen and trying to round those corners of the squares …

Gradients have been a part of the CSS spectrum for quite some time now. We see a lot of radial and linear gradients in a lot of projects, but there is one type of gradient that seems to be a bit lonely: the conic gradient. We’re going to make a watch face using this type …
