    <Divclass= "Parent">        <imgclass= "image"src= "http://h.hiphotos.baidu.com/baike/c0%3Dbaike80%2C5%2C5%2C80%2C26/sign=94d19969d40735fa85fd46ebff3864d6/ 8644ebf81a4c510fe630d9686059252dd52aa5cf.jpg "/>        <Divclass= "Progress">75%</Div>    </Div>

CSS section:

. Parent{/*set the absolute positioning of the relative positioning Mate Progress display block*/position:relative;/*set the float, let the width shrink, wrap the picture, otherwise too wide, it will appear the width of the progress display block is greater than the width of the picture*/float: Left;}.

Originally want to use CSS attr function, let progress information only appear in one place, but currently attr function can not be used in the properties outside the content, had to stop.
