Answer 1

You can consider fixed the linear-gradient but animate background-position instead,
Use background shorthand background:linear-gradient(to left,white ,yellow) left center/0% no-repeat; where 0% is the background-position.
Use background-position 200% if want to fully cover up background with full color at the end of animation.
