Roman Komarov forked a demo of mine the other day and showed how CSS scroll driven animation could map the input[type=range]
slider's thumb pseudo element position and use it to power a percentage in a gradient mask.
Roman explains it all very well here on their blog.
It's super rad. And totally triggered 2 ideas…
FORK THE FORK!!! #
The first idea I was able to finish tonight, and the 2nd I'll do sometime soon. Ssssecretssss
Here's my fork of their fork, repurposed their mapping to power the fill of a range slider. A task that's not so easy.
I left a good chunk of comments in there!
While this may not have great support at the moment, and is quite a little web of CSS to setup… it's a very promising path forward for styling input[type=range]
and other components with moveable parts.
I'll be stashing this into my CSS tricks 🪦
