If you want to make a masking animation on HTML, usually can make using height transition and overflow: hidden.
\nIt’s fine on your desktop browser, but it’s not smooth on mobile devices.
\nThe performance of animating some elements (such as width, height, left, top and margin..etc) are not that great on mobile devices.
\nThe best things for smooth animation are CSS3 transitions, CSS3 3D transforms, Canvas Drawing and WebGL, because these things are using GPU acceleration.
\nI’ve tested three ways (Height, ScaleY, Translate) for smooth animations, you can see my demo at below url.

1. Height animation<\/h3>\n

It’s very simple way for the masking animation.
\nBut the performance is bad on mobile devices, the animation is not smooth.<\/p>\n
