1.最好使用背景图尺寸正好的

2.引入文件

background-image: url(../img/ui-user.png);

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='../img/ui-user.png',sizingMethod='scale')";

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='../img/ui-user.png',sizingMethod='scale');

-ms-behavior: url(../css/backgroundsize.min.htc);

display: block;

background-position: center;

background-repeat: no-repeat;

background-size: contain;

-ms-behavior: url(../css/backgroundsize.min.htc);
