Using React Portals to Render Children Outside the DOM Hierarchy

15.1.2019
Say we need to render a child element into a React application. Easy right? That child is mounted to the nearest DOM element and rendered inside of it as a result. render() { return ( <div> // Child to render inside of the div </div> ); } But! What if we want...

Design v17

14.1.2019
We rolled out a new site design on January 1! This is the 17th version of CSS-Tricks if you can believe that. The versions tend to evolve a decent amount beyond the initial launch, but we archive screenshots on this design history page. Like I said in our 2018 thank you post: This is easily...

The Ethics of Web Performance

14.1.2019
Tim Kadlec on the issues surrounding poor web performance and why it’s so important for us to care about making our sites as fast as possible: Poor performance can, and does, lead to exclusion. This point is extremely well documented by now, but warrants repeating. Sites that use an excess...

Slice and Dice a Disc with CSS

13.1.2019
I recently came across an interesting sliced disc design. The disc had a diagonal gradient and was split into horizontal slices, offset a bit from left to right. Naturally, I started to think what would the most efficient way of doing it with CSS be. Sliced gradient disc. The first thought...

Colorized Brackets for IDE

13.1.2019
Coders treat their text editors and IDE’s like fragile beings, and for good reason: we spend a ton of time in them and having our tweaks and extensions can make us incredibly productive for our personal workflows. I always love hearing about what extensions and workflows other developers...

Re: Pleasing Color Palettes

11.1.2019
There are so many tools out there to help you pick colors. I totally get it! It's hard! When colors are done well, it's like magic. It adds a level of polish to a design that can really set it apart. Let's look at some, then talk about this idea some more. Here's one I just saw called Color...

Piecing Together Approaches for a CSS Masonry Layout

11.1.2019
Masonry layout, on the web, is when items of an uneven size are laid out such that there aren't uneven gaps. I would guess the term was coined (or at least popularized) for the web by David DeSandro because of his popular Masonry JavaScript library, which has been around since 2010. JavaScript...

Why we need CSS subgrid

11.1.2019
I’m a huge fan of CSS Grid and I use it on pretty much every project these days. However, there’s one part of it that makes things much more complicated than they really ought to be: the lack of subgrids. And in this post on the matter, Ken Bellows explains why they’d be so gosh darn useful: But...

Converting Color Spaces in JavaScript

10.1.2019
A challenge I faced in building an image "emojifier" was that I needed to change the color spaces of values obtained using getImageData() from RGB to HSL. I used arrays of emojis arranged by brightness and saturation, and they were HSL-based for the best matches of average pixel colors with...

Algorithmic Layouts

10.1.2019
Don't miss this video by Heydon that digs into CSS layouts. It's great how he combines fundamental knowledge, like the way elements flow, wrap, and can have margin with new layout methods like flexbox and grid (with specific examples). Of particular note is the clear demonstration of how flexbox...

Git Checkout at Previous Timeframe

9.1.2019
In the past I’ve blogged about checking out branches created on a specific date as well as sorting git branches by date, but one frequent usage of git and dates is checking out a commit at a given time in the past. For example, I often say “Weird, this feature was working a month...

New ES2018 Features Every JavaScript Developer Should Know

9.1.2019
The ninth edition of the ECMAScript standard, officially known as ECMAScript 2018 (or ES2018 for short), was released in June 2018. Starting with ES2016, new versions of ECMAScript specifications are released yearly rather than every several years and add fewer features than major editions used...

Toggling Animations On and Off

9.1.2019
A nicely detailed tutorial by Kirupa that gets into how you might provide a UI with persisted options that control whether animations run or not. The trick is custom properties that control the movement: body { --toggle: 0; --playState: "paused"; } Which are used within animations...

Styling a Web Component

8.1.2019
This confused me for a bit here so I'm writing it out while it's fresh in mind. Just because you're using a web component doesn't mean the styles of it are entirely isolated. You might have content within a web component that is styled normally along with the rest of your website. Like this: See...
