1：圆角的兼容

 -moz-border-radius: 2px; /* Firefox */
  -webkit-border-radius: 2px; /* Safari 和 Chrome */
  border-radius: 2px; /* Opera 10.5+, 以及使用了IE-CSS3的IE浏览器 */
  -o-border-radius:2px;
  -khtml-border-radius: 2px;   /* 针对Konqueror浏览器 */

1：阴影

filter:alpha(opacity=100 finishopacity=50 style=1 startx=0,starty=0,finishx=0,finishy=150) progid:DXImageTransform.Microsoft.gradient(startcolorstr=red,endcolorstr=blue,gradientType=0);	
    -ms-filter:alpha(opacity=100 finishopacity=50 style=1 startx=0,starty=0,finishx=0,finishy=150) progid:DXImageTransform.Microsoft.gradient(startcolorstr=red,endcolorstr=blue,gradientType=0);
background:red; /* 一些不支持背景渐变的浏览器 */ 
background:-moz-linear-gradient(top, red, rgba(0, 0, 255, 0.5));
background:-webkit-gradient(linear, 0 0, 0 bottom, from(#ff0000), to(rgba(0, 0, 255, 0.5)));
