How make it alive?
First thought about CSS, right?
When it's good to use?
If we talk about CSS
Cases
-
the animation is simple (e.g., button hover animation)
-
the animation should work even if JS is disabled (e.g., loading bar)
What about JS?
Cases
-
the animation requires a complex timeline
-
the animation is not supported in CSS or works better with JS animation.
Why you think so?
Blame for GPU!
Javascript > Style > Layout > Paint > Composite
Browser renders a webpage
We have for animation
60
frames per second
16
ms to spend for each frame
