13.10.2020
Some very cool news from Netlify: Edge Handlers are in Early Access (request it here). I think these couple of lines of code do a great job in explaining what an Edge Handler is:
export function onRequest(event) {

Web Technologies and Syntax

JavaScript has a (newish) feature called optional chaining. Say I have code like:
const name = Data.person.name;
If person happens to not exist on Data, I’m going to get a hard, show-stopping error. With optional chaining, I can write:
const name = Data.person?.name;
Now if person...

Weaved Webs
17.9.2020
There is a bit of an irony with Jamstack.
The concept is simple: you put pre-rendered, static files on web hosting (a CDN) designed to do that well. That’s it. If you need to do more, anything you do from there is done with client-side JavaScript, which is likely talking to serverless...
AVIF has landed
8.9.2020
Everybody is talking about AVIF today because of Jake’s blog post. As the say, I was today years old when I learned AVIF was a thing. But thanks to web technology being ahead of the game for once, we can already take advantage of it.
This will be easier if you’ve abstracted your...
Working with JavaScript Media Queries
7.9.2020
What’s the first thing that comes to mind when you think of media queries? Maybe something in a CSS file that looks like this:

body {
background-color: tomato;
}
}
CSS media queries are a core ingredient in any responsive...

Using @property for CSS Custom Properties
3.9.2020
Una Kravetz digs into how Chrome now allows you to declare CSS custom properties directly from CSS with more information than just a string.
So rather than something like this:
html {

}
…can be declared with more details like this:
@property --stop {

Excluding Emojis From Transparent Text Clipping
2.9.2020
CSS-Tricks has this pretty cool way of styling hovered links. By default, the text is a fairly common blue. But hover of the links, and they’re filled with a linear gradient.
😍
Pretty neat, right? And the trick isn’t all that complicated. On hover…

Copy the Browser’s Native Focus Styles
28.8.2020
Remy documented this the other day. Firefox supports a Highlight keyword and both Chrome and Safari support a -webkit-focus-ring-color keyword. So if you, for example, have removed focus from something and want to put it back in the same style as the browser default, or want to apply a focus style...

leading-trim is a suggested new CSS property that lets us remove the extra spacing in every font so that we can more predictably style text. Ethan Wang has written about it — including how Microsoft has advocated for it — and that it’s now part of the Inline Layout Module Level 3 spec.

More Control Over CSS Borders With background-image
7.8.2020
You can make a typical CSS border dashed or dotted. For example:
.box {
border: 1px dashed black;
border: 3px dotted red;
}
You don’t have all that much control over how big or long the dashes or gaps are. And you certainly can’t give the dashes slants, fading, or animation!...
What does 100% mean in CSS?

When using percentage values in CSS like this…
.element {
margin-top: 40%;
}
…what does that % value mean here? What is it a percentage of? There’ve been so many times when I’ll be using percentages and something weird happens. I typically shrug, change the value to something else...

You know the title attribute? I can do this:
<div title="The Title"I'm a div with a `title`
