Revisiting the Rendering Tier

5.4.2019
Have you ever created a well-intentioned, thoughtful design system only to watch it grow into an ever-increasing and scary codebase? I've been working in sort of the opposite direction, inheriting the scary codebase and trying to create a thoughtful system from it. Here's Alex Sanders on the topic...

A Couple of New Wufoo Tips

4.4.2019
(This is a sponsored post.) High fives to Wufoo, our long-time sponsor here on CSS-Tricks. It's powered the vast majority of forms I've built over the past decade. If you've never used it or heard of it: it's a form builder. It makes the arduous task of implementing forms trivially easy. Building...

KV Storage

1.4.2019
localStorage is... Good! It's an incredibly easy API to use. localStorage.setItem('name', 'Chris'); let name = localStorage.getItem('name'); Bad! Philip Walton explains why: localStorage is a synchronous API that blocks the main thread, and any time you access it you potentially prevent your...

Breaking CSS Custom Properties out of :root Might Be a Good Idea

27.3.2019
CSS Custom Properties have been a hot topic for a while now, with tons of great articles about them, from great primers on how they work to creative tutorials to do some real magic with them. If you’ve read more than one or two articles on the topic, then I’m sure you’ve noticed that they start...

Buddy: 15 Minutes to Automation Nirvana

26.3.2019
(This is a sponsored post.) Deploying a website to the server in 2019 requires much more effort than 10 years ago. For example, here's what needs to be done nowadays to deliver a typical JS app: split the app into chunks configure webpack bundle minify .js files set up staging environment upload...

Understanding Event Emitters

26.3.2019
Consider, a DOM Event: const button = document.querySelector("button"); button.addEventListener("click", (event) => /* do something with the event */) We added a listener to a button click. We’ve subscribed to an event being emitted and we fire a callback when it does. Every time we click that...

Advanced Tooling for Web Components

22.3.2019
Over the course of the last four articles in this five-part series, we’ve taken a broad look at the technologies that make up the Web Components standards. First, we looked at how to create HTML templates that could be consumed at a later time. Second, we dove into creating our own custom element....

See No Evil: Hidden Content and Accessibility

15.3.2019
There is no one true way to hide something on the web. Nor should there be, because hiding is too vague. Are you hiding visually or temporarily (like a user menu), but the content should still be accessible? Are you hiding it from assistive tech on purpose? Are you showing it to assistive tech...

Planning for Responsive Images

13.3.2019
The first time I made an image responsive, it was as simple as coding these four lines: img { max-width: 100%; height auto; /* default */ } Though that worked for me as a developer, it wasn’t the best for the audience. What happens if the the image in the src attribute is heavy? On high-end...

How to Set Commit Author

13.3.2019
I’ve worn dozens of hats on a dozen different teams during my time at Mozilla, but none has been as rewarding and challenging as community management. Whether it’s mentoring students, welcoming new contributors, or reviewing pull requests, there’s always so much to be done....

Downsides of Smooth Scrolling

11.3.2019
Smooth scrolling has gotten a lot easier. If you want it all the time on your page, and you are happy letting the browser deal with the duration for you, it's a single line of CSS: html { scroll-behavior: smooth; } I tried this on version 17 of this site, and it was the second most-hated thing...

The Bottleneck of the Web

5.3.2019
Steve Souders, "JavaScript Dominates Browser CPU": Ten years ago the network was the main bottleneck. Today, the main bottleneck is JavaScript. The amount of JavaScript on pages is growing rapidly (nearly 5x in the last 7 years). In order to keep pages rendering and feeling fast, we need to focus...
