A gem from Chris Ferdinandi that details how to use custom events to hook into Web Components. More importantly, Chris dutifully explains why custom events are a better fit than, say, callback functions. With a typical JavaScript library, you pass callbacks in as part of the instantiate process. […] Because Web Components self-instantiate, though, there‚Äôs no easy way to do that. There’s a way to use callback functions, just not an “easy” way to go about it.

Hey look at that, the State of CSS Survey for 2024 is open and taking submissions.

I did this morning on the way to work (read: whatever cafe I fancy). There’s a pattern to it, right? Stop, go, stop, go, stop… it’s almost rhythmic and harmonious in the most annoying of ways.

A client asked if we could mimic the “rubber band” scrolling behavior on many mobile devices. I’m sure you know what I’m talking about. It’s a behavior that already exists and happens automatically in most browsers. In iOS Safari, for example, you’re allowed to scroll beyond the top or bottom edge of the viewport by a few hundred pixels, and letting go snaps the page back in place.

A couple of weeks ago I was super excited about publishing my first CSS-Tricks post: “Letter Spacing is Broken. Forget about that though, what’s important is the post’s topic: letter spacing is broken and doesn’t work as the CSS Specification says it should. In a nutshell, instead of spacing the characters evenly, it leaves an unpleasant space at the end of the element.

I can’t say I would have ever expected to see Jeremy Keith performing the Yeah Yeah Yeahs song “Maps”, but then again, I don’t know what I expected to happen at Frostapalooza. Brad Frost, web designer, author of Atomic Design, and an absolute maniac on the bass, celebrated his birthday by putting together a one-night-only benefit concert featuring musical performances by himself and his talented family and friends.

Every programming language has loops. Loops perform an operation (i.e., a chunk of work) a number of times, usually once for every item in an array or list, or to simply repeat an operation until a certain condition is met. JavaScript in particular has quite a few different types of loops. I haven’t even used all of them, so for my own curiosity, I thought I’d do a high-level overview of them. And as it turns out, there are pretty good reasons I haven’t used at least a couple of the different types.

I was just going over the latest CSSWG minutes (you can subscribe to them at W3C.org) and came across a few interesting nuggets I wanted to jot down for another time. The group discussed the CSS Values, CSS Easing, and Selectors modules, but what really caught my eye was adding triggered delays to CSS for things like hover, long taps, and focus states. The idea stems from an OpenUI proposal, the same group we can thank for raising things like the Popover API and customizable select element.

Yes, yes. Functionally, they are different. But heck if I didn’t know about the wacky thresholds until Jens Oliver Meiert tooted a pair of quick polls. According to the HTML Standard: If the current cell has a colspan attribute, then , and let colspan be the result. If parsing that value failed, or returned zero, or if the attribute is absent, then let colspan be 1, instead. If colspan is greater than 1000, let it be 1000 instead.
