GSAP is one for the front-end people who like to sweat the details crafting joyful digital experiences.
And it's been around for a loooong time – I remember using it back in the Flash ActionScript days in the early noughts.
And the reason I'm posting it here, beyond giving it a push? Well it has finally had a beautiful rebrand and new site, better organising the offering. Wonderful stuff.
