high cpu usage

[bazo]

the animations are cool and pretty, but one loader on a page can make firefox spike my cpu to around 50%

so they're not really usable...

I'm experiencing the same problem... If the spinner is shown for more than just one or two seconds, it has a huge performance impact.

The first comment was in 2014 ???? and the issue still open since then :/ :/ the spinners are awesome but I am not gonna use them :/ also can't get the spinner centered vertically, not sure even if this project is maintained

@medbouzid this issue is really dependant on browser vendors improving their CSS animation performance. There isn't much this project can change to improve performance.
