xm

21.10.2020
This is a neat little HTML preprocessor from Giuseppe Gurgone. It has very few features, but one of them is HTML includes, which is something I continue to be baffled that HTML doesn’t support natively. There are loads of ways to handle it. I think it’s silly that it’s been...

“Durable”

20.10.2020
Looks like the word “durable” is an emerging term in the world of serverless. As I understand it, it’s like allowing for state in places you wouldn’t normally expect to have it. For example, you call some cloud function and run some JavaScript… unless you have it...

How to Prevent Pasting into an Input

19.10.2020
Every once in a while I get to a website that doesn’t allow me to paste into a form input. In most cases it’s something to do with login credentials (username and or password) and auth codes. So how are they preventing me from pasting information? It’s as easy as you’d...

Parsel: A tiny, permissive CSS selector parser

2.10.2020
If you’ve ever thought to yourself, gosh, self, I wish I could have an Abstract Syntax Tree (AST) of this CSS selector, Lea has your back. If you’ve ever thought that same thing for an entire CSS file, that’s what PostCSS is, which has gone v8. PostCSS doesn’t do anything...

Web Technologies and Syntax

24.9.2020
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...

Virtual Event Registrations with Wufoo Forms

15.9.2020
(This is a sponsored post.) We’ve seen many events shift from in-person to online this year. That may have required a huge change to how you collect attendee registrations in the past, but with a paid Wufoo account and Zoom — along with a sprinkle of Zapier — it’s easier than ever to...

Modifying Specific Letters with CSS and JavaScript

10.9.2020
Changing specific characters can be a challenge in CSS. Often, we’re forced to implement our desired changes one-by-one in HTML, perhaps using the span element. But, in a few specific cases, a CSS-focused solution may still be possible. In this article, we’ll start by looking at some CSS-first...

Using max() for an inner-element max-width

7.9.2020
I go into all this in The “Inside” Problem. The gist: you want an edge-to-edge container, but the content inside to have a limited width. I think there is absolutely no problem using a nested element inside, but it’s also fun to look at the possibilities of making that work on...
