The Browser Can Remember Edited Content
22.5.2019
You can make the text inside any HTML element editable by adding the contenteditable attribute.
<div contenteditable>
Hey, I'm like a textarea kinda now!
</div>
I wouldn't say there are wheelbarrows full of use-cases for that, but it's neat. One possible use might be...
Anchor a Document or File to the BCH Chain With Notary.Bitcoin.com
19.5.2019
In my last article, I explained how to prove ownership of a specific address by signing a message with a public and private key pair. That’s just one way of proving ownership and verifying a valid signature, as BCH users can also anchor a document to the chain using the Bitcoin Cash...
Footnotes That Work in RSS Readers
17.5.2019
Feedbin is the RSS reader I'm using at the moment. I was reading one of Harry's blog posts on it the other day, and I noticed a nice little interactive touch right inside Feedbin. There was a button-looking element with the number one which, as it turned out, was a footnote. I hovered over it,...
Everything You Ever Wanted to Know About inputmode
17.5.2019
The inputmode global attribute provides a hint to browsers for devices with onscreen keyboards to help them decide which keyboard to display when a user has selected any input or textarea element.
<input type="text" inputmode="" />
<textarea inputmode="" />
Unlike changing the type...

Using Array reduce
14.5.2019
Every developer who specializes in any programming language will tell you there’s a powerful tool the language provides that they rarely use and wish they knew more about. For me, it’s Array.prototype.reduce. I quite enjoy the other Array methods like map, filter, and find, but reduce...
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.
.auto-grid...
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...
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...
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"...
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...
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()...
7 Useful JavaScript Tricks
16.4.2019
Just like every other programming language, JavaScript has dozens of tricks to accomplish both easy and difficult tasks. Some tricks are widely known while others are enough to blow your mind. Let’s have a look at {x} JavaScript tricks you can start using today! Get Unique Values of an Array...
Get a CSS Custom Property Value with JavaScript
11.4.2019
Here’s a neat trick from Andy Bell where he uses CSS Custom Properties to check if a particular CSS feature is supported by using JavaScript.
Basically, he's using the ability CSS has to check for browser support on a particular property, setting a custom property that returns a value of either...
Using “box shadows” and clip-path together
11.4.2019
Let's do a little step-by-step of a situation where you can't quite do what seems to make sense, but you can still get it done with CSS trickery. In this case, it'll be applying a shadow to a shape.
You make a box
.tag {
background: #FB8C00;
color: #222;
font: bold 32px system-ui;
padding:...
Native Lazy Loading
9.4.2019
IntersectionObserver has made lazy loading a lot easier and more efficient than it used to be, but to do it really right you still gotta remove the src and such, which is cumbersome. It's definitely not as easy as:
<img src="celebration.jpg" loading="lazy" alt="..." />

Fixed Headers, On-Page Links, and Overlapping Content, Oh My!
3.4.2019
Let's take a basic on-page link:
<a href="#section-two">Section Two</a>
When clicked, the browser will scroll itself to the element with that ID: <section id="section-two"></section>. A browser feature as old as browsers themselves, just about.
But as soon as...
KV Storage

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...
