How can a grow/shrink animation be done with jQuery and/or CSS? An example that I can think of is this when you click on the Join Now button.
I looked into animate.css but they did not offer such an animation.
回答1:
DEMO — Solution using CSS3's transition-duration (W3Schools) and transform:scale(X,Y); (W3Schools).
Update:
DEMO — Going a step further, doing more than just changing to opacity:0; by adding display:none; (via jQuery .hide()) at the end of the animation.
