Brief tutorial

This is an animation special effect made by using pure CSS3 to slide the mouse over the image mask layer. In this special effect, when the mouse slides over or hovers over the image, a mask layer animation will appear on the image, showing the image description information and link icon button.

Usage

Introduce bootstrap style files and font-awesome font icon files into the page.

<link rel="stylesheet" type="text/css" href="path/to/css/bootstrap.min.css">
<link rel="stylesheet" type="text/css" href="path/to/css/font-awesome.min.css">
