Js implements slow div layer contraction and expansion, and jsdiv layer Expansion

This is a special effect code for layer scaling and expansion. It has a bit of animation effect and is slow to expand. It looks good if it is jointly created by DIV + JS. Without content constraints, the speed of contraction and expansion can be controlled, and the height and cycle time can also be changed.
