If you’re looking for a primer on CSS specificity, we’ve got that. And if you’re trying to get ahead of the game, you should be aware of CSS Cascade Layers as well.

 Nic Chan: … the will-change property landed in major browsers in August 2015, and I’ve been on the lookout for when to use it ever since. It might seem self-evident to apply it to commonly animated properties such as transform or opacity, but the browser already classifies them as composite properties, thus, they are known as the few …

For the past few weeks, I’ve been hiring for a senior full-stack JavaScript engineer at my rental furniture company, Pabio. Since we’re a remote team, we conduct our interviews on Zoom, and I’ve observed that some developers are not great at live-coding or whiteboard interviews, even if they’re good at the job. So, instead, we …

In recent years, the Jamstack methodology for building websites has become increasingly popular. Performance, scalable, and secure, it’s easy to see why it’s becoming an attractive way to build websites for developers. GatsbyJS is a static site generator platform. It’s powered by React, a front-end JavaScript library, for building user interfaces. And uses GraphQL, an …

Kinda silly sounding, isn’t it? CSS database queries. But, hey, CSS is capable of talking to other languages in the sense that it can set the values of things that they can read. Plus, CSS can request other files, and I suppose a server could respond to that request with something it requested from a …

Let’s face it: building an AA or AAA-accessible product can be quite daunting. Luckily, having an accessible product isn’t all-or-nothing. Even seemingly small improvements can have nice quality of life benefits for many people. In that spirit, here are five accessibility quick wins you can implement today.

That’s a damn one-two punch from Dave. He goes for the ultimate clickbait title¹, then follows up with a pile of epic advice for us all. If you want web browsers to get better, listen up: Complaining on Twitter sure does feel good but it doesn’t do much other than burning bridges and burning through …

On several occasions, I’ve needed to send off an HTTP request with some data to log when a user does something like navigate to a different page or submit a form. Consider this contrived example of sending some information to an external service when a link is clicked: There’s nothing terribly complicated going on here. …

This is your complete guide to CSS cascade layers, a CSS feature that allows us to define explicit contained layers of specificity, so that we have full control over which styles take priority in a project without relying on specificity hacks or !important. This guide is intended to help you fully understand what cascade layers …

Being able to understand Node continues to be an important skill if you’re a front-end developer. Deno has arrived as another way to run JavaScript outside the browser, but the huge ecosystem of tools and software built with Node mean it’s not going anywhere anytime soon. If you’ve mainly written JavaScript that runs in the …

I linked to Jay’s front-end predictions last year and I think they panned out pretty well. I think he’s got a bit of a knack for that wide-scope look at front-end, including tooling and architecture, as well as browser tech. Let’s review.

Font Awesome is an incredibly popular icon library. Unfortunately, it’s somewhat easy to use in a way that results in less-than-ideal performance. By subsetting Font Awesome, we can remove any unused glyphs from the font files it provides. This will reduce the number of bytes transmitted over the wire, and improve performance. Let’s subset fonts …

First things first, if you didn’t know Netlify had a CLI, they do.  One of my favorite things about it running the command netlify dev on nearly any static-site generator project is seeing it detect what it should be doing and spinning the site up in a dev server for you. But not just any dev …

A useful little UI widget thingy here from Jens Kuerschner. Click the add-to-calendar button, get a list of calendar apps, the user selects which one they actually use, and they get what they need for that calendar. Could be a specialized URL they get sent to, or even an .ics file that gets downloaded.

Within Drupal 10 core, we’re implementing a new auto-filling CSS Grid technique that I think is cool enough to share with the world. The requirements are: The user specifies a maximum number of columns. This is the auto-filling grid’s “natural” state. If a grid cell goes under a user-specified width, the auto-filling grid will readjust …

Greensock made the GSAP Flip plugin free in the 3.9 release. FLIP is an animation concept that helps make super performance state-change animations. Ryan Mulligan has a good blog post: FLIP, coined by Paul Lewis, is an acronym for First, Last, Invert, and Play. The Flip plugin harnesses this technique so that web developers can effortlessly …

Creating CSS link hover effects can add a bit of flair to an otherwise bland webpage. If you’ve ever found yourself stumped trying to make a slick hover effect, then I have six CSS effects for you to take and use for your next project.

✋ High fives to WordPress for releasing version 5.9 on January 29! This was the long-awaited introduction of the Site Editor and the reverberations are still being felt across the 43% slice of the web that is powered by WordPress. The Site Editor is more than a neat feature: it’s a completely new approach to …

Last year, Elise Blanchard did some great historical research and discovered that blue hyperlinks replaced black hyperlinks in 1993. They’ve been blue for so long now that the general advice I always hear is to keep them that way. There is powerful societal muscle memory for “blue text is a clickable link.” BUT WHY?!

The File System Access API is a web API that allows read and write access to a user’s local files. It unlocks new capabilities to build powerful web applications, such as text editors or IDEs, image editing tools, improved import/export, all in the frontend. Let’s look into how to get started using this API.

Kilian Valkhof: … Mobile Safari increases the default font-size when you switch a website from portrait to landscape. On phones that is, it doesn’t do it on iPad. Safari has been doing this for a long time, as a way to improve readability on non-mobile optimized websites. While undoubtedly useful in a time when literally …

Every now and then, I find that I’ve accumulated a bunch of links about various things I find interesting. Like React and JavaScript! Here’s a list of nine links to other articles about them that I’ve been saving up and think are worth sharing.

Imagine you have an element with a multi-value CSS property, such as transform: optional custom property values: Now imagine you don’t always want all the transform values to be applied, so some are optional. You might think of CSS optional custom property values:

I was just writing in my “What’s new in since CSS3?” article about recent and possible future changes to CSS colors. It’s weirdly a lot. There are just as many or more new and upcoming ways to define colors than what we have now. I thought we’d take a really quick look. First, a major …

This is a wonderful roundup from Jeremy, who I picture circling January 1, 2022, in red marker on a giant paper calendar back in 2008 and patiently counting the days. See, there was a little smattering of internet drama back in 2008 (weird, right?) where Hixie kind of “officially speculated” that HTML5 would take 19 …

I recently rewrote one of my projects — Minimal Theme for Twitter — as a Next.js Chrome extension because I wanted to use React for the pop-up. Using React would allow me to clearly separate my extension’s pop-up component and its application logic from its content scripts, which are the CSS and JavaScript files needed …

Cloudinary is a host for your digital assets like images and video. If you don’t already know them, you should, because you can build it into the asset management you almost certainly need to do if you run any size of website. Cloudinary helps you serve the assets as efficiently as technologically possible, meaning optimization, …

Say you have a bitmap graphic — like a JPG, PNG, or GIF — and you wish it was vector, like SVG. What do you do? You could trace it yourself in some kind of design software. Or tools within design software can help. (I don’t wanna delay the lede here, there is a free …

I was updating my portfolio and wanted to use the forward slash (/) as a visual element for the site’s main layout. I hadn’t attempted to create a slanted container in CSS before, but it seemed like it would be easy at first glance. As I began digging into it more, however, there were actually …

There is a code snippet that I see all the time when the media query prefers-reduced-motion is talked about. Here it is: This is CSS that attempts to obliterate any motion on a website under the condition that the user has specified a preference for reduced motion in the accessibility preferences of their operating system.
