Firefox DevTools WebConsole 2018 retrospective


Here’s a wonderful post by Nicolas Chevobbe on what the Firefox DevTools team was up to last year. What strikes me is how many improvements they shipped — from big visual design improvements to tiny usability fixes that help us make sure our code works as we expect it to in the console....

A Quick CSS Audit and General Notes About Design Systems


I’ve been auditing a ton of CSS lately and thought it would be neat to jot down how I’m going about doing that. I’m sure there are a million different ways to do this depending on the size and scale of your app and how your CSS works under the hood, so please take all this with a grain of salt....

Google Fonts and font-display


The font-display descriptor in @font-face blocks is really great. It goes a long way, all by itself, for improving the perceived performance of web font loading. Loading web fonts is tricky stuff and having a tool like this that works as well as it does is a big deal for the web. It's such a...

What makes someone a good front-end developer?


We recently covered this exact same thing, but from the perspective of a bunch of developers. Chris Ferdinandi weighs in: The least important skills for a front-end developer to have are technical ones. The nuances of JavaScript. How to use a particular library, framework, or build tool. How...

Why isn’t it <style src=””>?


The way JavaScript works is we can do scripts as an inline block: &#60;script&#62; let foo = "bar"; &#60;/script&#62; Or, if the script should be fetched from the network... &#60;script src="/js/global.js"&#62;&#60;/script&#62; With CSS, we can do an inline block of styles: &#60;style&#62; .foo...

Google Labs Web Components


I think it's kinda cool to see Google dropping repos of interesting web components. It demonstrates the possibilities of cool new web features and allows them to ship them in a way that's compatible with entirely web standards. Here's one: &#60;two-up&#62; I wanted to give it a try, so I linked...

What do you name color variables?


What naming scheme do you use for color variables? Have you succeeded at writing CSS that uses color variables in a manner agnostic to the colors they represent?I&#39;ve tried all of the following, and I have yet to succeed at writing CSS that works well with any color scheme....

Build a state management system with vanilla JavaScript


Managing state is not a new thing in software, but it’s still relatively new for building software in JavaScript. Traditionally, we’d keep state within the DOM itself or even assign it to a global object in the window. Now though, we’re spoiled with choices for libraries and frameworks to help...

Script & Style Show: Episode 15: CSP with Scott Helme


In this episode:  Todd dials in from a poppin&#8217; KCDC while David dials in with a massive headache.  Scott Helme dials in from lovely Manchester to discuss web security, specifically the criminally underused CSP API.  Join us to learn what CSP is, why it&#8217;s important, how it works,...

Fast, Good, Local Site Search with Jetpack


If you have, say, 20 posts/pages on your WordPress site, the search functionality that is baked right into your self-hosted WordPress site will probably do a great job. Search is a pretty cool feature to ship with WordPress, truth be told. But as a site grows, you'll find limits. How it works...

Animate Calligraphy with SVG


From time to time at Stackoverflow, the question pops up whether there is an equivalent to the stroke-dashoffset technique for animating the SVG stroke that works for the fill attribute. But upon closer inspection, what the questions are really trying to ask is something like this: I have something...

Custom List Number Styling


How about a classic CSS trick! This isn't even so tricky anymore, since CSS has counter-increment and counter-reset and such that is perfect for this. I just wanted to make sure you knew how it works and had some easy-to-copy examples at the ready. Let's say all you wanna do is style the dang...

How React Reconciliation Works


React is fast! Some of that speed comes from updating only the parts of the DOM that need it. Less for you to worry about and a speed gain to boot. As long as you understand the workings of setState(), you should be good to go. However, it’s also important to familiarize yourself with how this...

Locate and identify website visitors by IP address


(This is a sponsored post.) Big thanks to ipstack for sponsoring CSS-Tricks this week! Have you ever had the need to know the general location of a visitor of your website? You can get that information, without having to explicitly ask for it, by the user’s IP address. You’re just going to need...

Inspecting Animations in DevTools


I stumbled upon the Animation panel in Chrome’s DevTools the other day and almost jumped out of my seat with pure joy. Not only was I completely unaware that such a thing exists, but it was better than what I could’ve hoped: it lets you control and manipulate CSS animations and visualize...

CSS Blocks


A new entry into the CSS-in-JS landscape! Looks like the idea is that you write an individual CSS file for every component. You have to work in components, that's how the whole thing works. In the same isle as styled-components, css-modules, and glamorous. Then you write :scope { } which is...
