The Thinking Behind Simplifying Event Handlers
9.5.2019
Events are used to respond when a user clicks somewhere, focuses on a link with their keyboard, and changes the text in a form. When I first started learning JavaScript, I wrote complicated event listeners. More recently, I've learned how to reduce both the amount of code I write and the number...
A responsive grid layout with no media queries
9.5.2019
Andy Bell made a really cool demo that shows us how to create a responsive grid layout without any media queries at all. It happens to look like this when you change the size of the browser window:
I think this is a wonderful layout technique that’s just 6 lines (!) of CSS.

New ECMAScript Modules in Node v12

If you’re familiar with popular JavaScript frontend frameworks like React, Angular, etc, then the concept of ECMAScript won’t be entirely new to you. ES Modules have the import and
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...
A CSS Golfing Exercise

Code golfing is a type of programming where the goal is to accomplish a task using as few bytes as possible. CSSBattle is a code golfing battleground where players complete to recreate target images using CSS and HTML.

Split
2.5.2019
Jeremy on the divide between the core languages of the web, and all the tooling that exists to produce code in those languages:
On the one hand, you’ve got the raw materials of the web: HTML, CSS, and JavaScript. This is what users will ultimately interact with.
On the other hand, you’ve got...
Naming things to improve accessibility
2.5.2019
I like the this wrap-up statement from Hidde de Vries:
In modern browsers, our markup becomes an accessibility tree that ultimately informs what our interface looks like to assistive technologies. It doesn’t matter as much whether you’ve written this markup:
in a .html file
in Twig, Handlebars...
The Simplest Ways to Handle HTML Includes
30.4.2019
It's extremely surprising to me that HTML has never had any way to include other HTML files within it. Nor does there seem to be anything on the horizon that addresses it. I'm talking about straight up includes, like taking a chunk of HTML and plopping it right into another. For example the...
Revisiting prefers-reduced-motion, the reduced motion media query
30.4.2019
Two years ago, I wrote about prefers-reduced-motion, a media query introduced into Safari 10.1 to help people with vestibular and seizure disorders use the web. The article provided some background about the media query, why it was needed, and how to work with it to avoid creating...
JavaScript Detect Async Function
29.4.2019
JavaScript async/await has changed the landscape of how we code. We’re no longer stuck in callback or then hell, and our code can feel more “top down” again. Async functions require the following syntax: async function myFunction() { } To use await with a function, the function...

Corvid by Wix: Accelerated Development of Web Applications
25.4.2019
(This is a sponsored post.)
It's been interesting to watch Wix evolve from a website builder into a full-fledged platform for developing web applications. It's still just as easy for anyone to spin up a website with the visual builder that's always been there, but Wix Code was introduced a little...
Using Parcel as a Bundler for React Applications
25.4.2019
You may already be familiar with webpack for asset management on projects. However, there’s another cool tool out there called Parcel, which is comparable to webpack in that it helps with hassle-free asset bundling. Where Parcel really shines is that it requires zero configuration to get up...

Preload, prefetch and other link tags
24.4.2019
Ivan Akulov has collected a whole bunch of information and know-how on making things load a bit more quickly with preload and prefetch. That's great in and of itself, but he also points to something new to me – the as attribute:
<link rel="preload" href="/style.css" as="style"...
The Circle of a React Lifecycle
23.4.2019
A React component goes through different phases as it lives in an application, though it might not be evident that anything is happening behind the scenes.
Those phases are:
mounting
updating
unmounting
error handling
There are methods in each of these phases that make it possible to perform...
Could Grouping HTML Classes Make Them More Readable?
22.4.2019
You can have multiple classes on an HTML element:
<div class="module p-2"></div>
Nothing incorrect or invalid there at all. It has two classes. In CSS, both of these will apply:
.module { }
.p-2 { }
const div...
Inclusively Hidden
19.4.2019
Scott O'Hara recently published "Inclusively Hidden," a nice walkthrough of the different ways to hide things on the web. Nothing is ever cut and dry when it comes to the web! What complicates this is that hidden begs the question: hidden for whom? Different answers to that have different...
Tabs: It’s Complicated™
19.4.2019
I've said before one quick and powerful thing you can learn as a front-end developer just getting starting with JavaScript is changing classes.
const button = document.querySelector(".my-button");
const element = document.querySelector(".content");
button.addEventListener("click", function()...
