Using requestAnimationFrame with React Hooks

21.8.2019
Animating with requestAnimationFrame should be easy, but if you haven’t read React’s documentation thoroughly then you will probably run into a few things that might cause you a headache. Here are three gotcha moments I learned the hard way. TLDR: Pass an empty array as a second parameter...

Pseudo Code

23.7.2019
Yonatan Doron wrote a post on Medium not long ago called "Art of Code — Why you should write more Pseudo Code." Love that title, as a fan of pseudo code myself. That is, writing "code" that describes something you want to do or communicate, but that isn't of any particular language and doesn't...

Using GraphQL Playground with Gatsby

18.7.2019
I’m assuming most of you have already heard about Gatsby, and at least loosely know that it’s basically a static site generator for React sites. It generally runs like this: Data Sources → Pull data from anywhere. Build → Generate your website with React and GraphQL. Deploy → Send the site to...

The Fight Against Layout Jank

11.7.2019
A web page isn't locked in stone just because it has rendered visually. Media assets, like images, can come in and cause the layout to shift based on their size, which typically isn't known in fluid layouts until they do render. Or fonts can load and reflow layout. Or XHRs can bring in more content...

The Twelfth Fourth

4.7.2019
CSS-Tricks is 12 years old! Firmly into that Early Adolescence stage, I'd say ;) As we do each year, let's reflect upon the past year. I'd better have something to say, right? Otherwise, John Prine would get mad at me. How the hell can a person go to work in the morning And come home in...

Graphical User Interfaces for Git

3.7.2019
Git is command-line-driven software, but that doesn't mean you have to use the command line to make it work. There are lots of options! Some of the deepest programmer nerds I know prefer to use GUIs for Git (Graphic User Interface, or you know, software you can see things and click stuff), and some...

Making width and flexible items play nice together

1.7.2019
The short answer: flex-shrink and flex-basis are probably what you’re lookin’ for. The long answer Let’s say you want to align an image and some text next to each other with like this: Now let's say you reach for flexbox to make it happen. Setting the parent element to display: flex; is a good...

Different Approaches for Creating a Staggered Animation

27.6.2019
Animating elements, at its most basic, is fairly straightforward. Define the keyframes. Name the animation. Call it on an element. But sometimes we need something a little more complex to get the right “feel" for the way things move. For example, a sound equalizer might use the same animation...

Movin’ Modals Along a Path

4.6.2019
Modals always be just appearin'. You might see one once in a while that slides in from one of the edges, or uses some kind of scale/opacity thing to appear from "above" or "below." But we can get weirder than that. Why not have them come in on an offset-path? Just a swoopy arc is kinda fun. ...

Prevent Page Scrolling When a Modal is Open

3.6.2019
Please stop me if you've heard this one before. You open a modal, scroll through it, close it, and wind up somewhere else on the page than you were when you opened the modal. That's because modals are elements on a page just like any other. It may stay in place (assuming that's what it's meant...

What Does it Mean to Be “Full Stack”?

21.5.2019
I was asked this recently by a fellow developer who was at the same web tech conference I was at. This developer had met a lot of new people who literally introduced themselves as full-stack developers sort of the way Bob Vance, Vance Refrigeration would on The Office, but it was Tony Frank...

Iterating a React Design with Styled Components

16.5.2019
In a perfect world, our projects would have unlimited resources and time. Our teams would begin coding with well thought out and highly refined UX designs. There would be consensus among developers about the best way to approach styling. There’d be one or more CSS gurus on the team who could ensure...

Change Color of SVG on Hover

13.5.2019
There are a lot of different ways to use SVG. Depending on which way, the tactic for recoloring that SVG in different states or conditions — :hover, :active, :focus, class name change, etc. — is different. Let's look at the ways. Inline SVG Inline SVG is my favorite way to use...

Getting To Know The MutationObserver API

8.5.2019
MutationObserver watches the DOM, specifically the places you tell it to, like: document.querySelector('#watch-this'); ...and it can tell you (trigger a callback) when stuff happens — like when a child is added, removed, changed, or a number of other things. I used it just the other day...
