Let's say you're rocking a JAMstack-style site (no server-side languages in use), but you want to do something rather dynamic like send an email. Not a problem! That's the whole point of JAMstack. It's not just static hosting. It's that plus doing anything else you wanna do through JavaScript and APIs.

Here's the setup: You need a service to help you send the email. Let's just pick Sparkpost out of a hat. There are a number of them, … Read article

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 = document.querySelector("div");
console.log(div.classList.contains("module")); // true
console.log(div.classList.contains("p-3"));    // false

But what about grouping them? All we have here is a space-separated string. Maybe that's fine. But maybe we can make things more clear!… Read article

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.… Read article

There is already an env() function in CSS, but it kinda came out of nowhere as an Apple thing for dealing with "The Notch" but it has made it's way to be a draft spec. The point will be for UAs or authors to declare variables that cannot be changed. Global const for CSS, sorta.… Read article

I wrote that using inline <svg></svg> icons makes for the best icon system. I still think that's true. It's the easiest possible way to drop an icon onto a page. No network request, perfectly styleable.

But inlining code has some drawbacks, one of which is that it doesn't take advantage of caching. You're making the browser read and process the same code over and over as you browse around. Not that big of a deal. There are much bigger … Read article

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.… Read article

Fonts are vector. Vector art with more points makes for larger files than vector art with fewer points. Custom fonts are downloaded. So, fonts with less points in their vector art are smaller. That's the theory anyway. Shall we see if there is any merit to it?… Read article

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="..." />

Websites have a tendency to decay all by themselves. Link rot, they call it. Unpaid domain name registrations. Companies that have gone out of business. Site owners that have lost interest. What's sadder than a 404? Landing on a holding page of a URL that used to exist, but now has fallen into the hands of some domain hoarder after it expired, hoping someone will pay a premium to get it back.

That stuff is no fun. But what … Read article
