The CSS animation-trigger property delays the start of a CSS animation until a specific trigger occurs. More specifically, it listens for a named trigger and controls how the animation plays or pauses in response. .element { animation: fade-in 0.35s ease-in-out both; animation-trigger: –trigger play-forwards play-backwards; } CodePen Embed Fallback This behavior has traditionally been JavaScript territory, typically…
Every website peaks on launch day and slowly drifts from there, not because it breaks, but because nobody has time to keep it current. Autonomous websites, continuously optimized by agents after launch, aim to change that. But take the idea seriously, and you quickly run into a problem that has nothing to do with technology:…
There was a fun little debate about color themes and UI/UX. There is some solid logic to having three states for a color theme toggle: Light Mode Dark Mode System Meaning: Be in Light Mode no matter what Be in Dark Mode no matter what Respect whatever the OS setting is That’s what we have…
Just looking at what Bramus shared the other day: /* Adding a base class */ .btn { padding: 0.5rem 1rem; border-radius: 4px; } /* Listing everything… yuck! */ .btn-primary, .btn-secondary, .btn-danger { padding: 0.5rem 1rem; border-radius: 4px; } /* Works, but performs badly */ [class^=”btn-“], [class*=” btn-“] { padding: 0.5rem 1rem; } /* Newly resolved…

Any embedded JavaScript unfortunately won’t run if you load an SVG file with an tag, but CSS animations work perfectly fine.

Stephen and Chris hop on to talk about the couple of weeks post 2.0 launch. Things are certainly different in 2.0! Literally the location of certain buttons is in a new place, and that requires folks to poke around a bit and figure it out. Some people just do that and it’s a non-issue. Some…
Exactly the kind of nerdy UI/UX discussion I love: Lea’s pushing back on light/dark mode implementations that display three state options for visitors: Light Dark System (core of the debate) Why show a System option at all when: […] a good two state control can actually express all three states — users just need to apply the…
Having that first response from the server to users browsers be, ya know, full of good, useful, renderable HTML is certainly better than an empty <div id=”app”>. You can feel it and see it in the filmstrip view of the site loading. Not to mention you need it for at least things like <meta> tags…
Test automation has always been a field that requires a lot of work. Quality assurance teams were often stuck in a cycle of fixing broken tests, maintaining scripts by hand, and updating locators in a way that wasn’t reliable. As software release processes got shorter, this old way of doing things had a hard time…
