7. 光标大小：

8. min-height: 最小高度兼容代码

.minheight500{min-height:500px;height:auto !important;height:500px;overflow:visible;}

9. 鼠标不允许点击：

cursor:not-allowed;

10. mac font: osx平台字体优化

font-family:"Hiragino Sans GB","Hiragino Sans GB W3",'微软雅黑';

11. 省略号：

.ellipsis{white-space:nowrap;overflow:hidden;text-overflow:ellipsis}

二. css 3 code

1. 渐变：

.a{background:-webkit-gradient(linear,left top,left bottom,from(#69bdf9),to(#4aa7e8));background:-moz-linear-gradient(top,#67bcf8,#3b96d6);background:-o-linear-gradient(top,#67bcf8,#3b96d6);background:linear-gradient(top,#67bcf8,#3b96d6);}

2.投影：

.b{box-shadow:inset 1px -1px 0 #f1f1f1;text-shadow:1px 1px 0px #630;}
filter:progid:DXImageTransform.Microsoft.gradient(enabled='true',startColorstr='#99000000',endColorstr='#99000000');background:rgba(0,0,0,.6);

background:rgba(0,0,0,0.5);filter:progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr='#50000000',endColorstr='#50000000')\9;

看哪个startColorstr和endColorstr，一共8位，后6位是RGB的颜色代码，前两位是16进制的

比如60%透明，就是256x0.6=154，再换算成16进制=9A

background-image:-ms-linear-gradient(top, #fff, #ddd); ie10渐变
