How to achieve continuously animation in jQuery
In the page I have an arrow, which is hide at the beginning. When I click a button, the arrow shows.

I want a feature that the arrow continuously becomes bigger and returns to the original size, and then becomes bigger again, showing an expression of paying attention to where it points.
