Those javascript animations had my CPU running at 100% while I was reading the article. I'm not sure I like this new web... can't we just go back to GIFs for simple stuff like that?
The only reason GIFs are a better solution for you (i.e. not taking 100% of the CPU resource) is because it's about a quality GIF render. What you really need is quality of the software that powers the alternative solutions.
