Here's how we'd pump up a balloon using the transform property: const balloon = document. If we didn't know anything about CSS variables, we'd probably do some style manipulation straight from JavaScript. Say we want to make a balloon pump, where you hit a button as fast as you can to "inflate" an HTML-style balloon. They're a bit like those $ variables preprocessors like SASS and LESS let you pull off, but with one huge benefit: you can change the value of these variables at runtime using JavaScript ? In case you haven't heard, CSS variables are kind of taking web development by storm right now. Just shift the color a little bit whenever you hover over the button, plus a little circular gradient for a "metallic" sheen.īut there's a bit of added spice that CSS can't pull off on its own: We need to track your cursor position to make this interactive! Luckily, this has gotten a lot easier over the years You won't even need a UI framework or state management to pull it off ? ? Brief primer on CSS variables The effect is pretty simple on the surface.

This isn't some "static" hover state that always looks the same. Has anyone done this directional lighting cursor interaction with CSS? /zLL7Sk6kW5- Jed Bridges July 1, 2020 You've seen the basics at this point fade-ins, growing and shrinking, color shifts, animated rainbow gradients, etc etc etc.īut there was one animation that inspired me recently (props to Keyframers for shouting it out!)
Hover states are probably the most fun a developer can have when a designer isn't looking.
