## prompt:
give me js lib/function that is called cssSelectorAnimationTrigger:
1. adds style to head
the style contains `* { animation-name: js-cssSelectorAnimationTrigger-test1 } @keyframe js-cssSelectorAnimationTrigger-test1 { }`
2. listens on event on css animation start
and detects if event.(animation name) is the same as 'js-cssSelectorAnimationTrigger-test1'
3. runs `event.target.style.backgroundColor = 'red'`
