As this animation got a little bit more popular, it got some serious hate. I just want to point out that this is a proof of concept. Not following the best practices, accessibility, browser support... but showcasing what can be done using web technologies.
I was just playing with animations trying to reacreate this mockup
I was inspired by. Full animation works only in browsers supporting caret-color
You can read more about front end development on my blog
. I plan to write a follow up how this animation was created.
