以下是常用的代码收集，没有任何技术含量，只是填坑的积累。转载请注明出处，谢谢。
1. 文字换行
/*强制不换行*/ white-space:nowrap; /*自动换行*/ word-wrap: break-word; word-break: normal; /*强制英文单词断行*/ word-break:break-all;
2. 两端对齐
text-align:justify;text-justify:inter-ideogra

去掉chrome记住密码后自动填充表单的黄色背景
4. ie6: position:fixed
.fixed-top /* position fixed Top */{position:fixed;bottom:auto;top:0; }
* html .fixed-top /* IE6 position fixed Top */{position:absolute;bottom:auto;top:expression(eval(document.documentElement.scrollTop));}
*html{background-image:url(about:blank);background-attachment:fixed;}
5. clearfix

6. seperate-table
.tab{border-collapse:separate;border:1px solid #e0e0e0;}
.tab th,.tab td{padding:3px;font-size:12px;background:#f5f9fb;border:1px solid;border-color:#fff #deedf6 #deedf6 #fff;}
.tab th{background:#edf4f0;}
.tab tr.even td{background:#fff;}
<table class="tab" width="100%" cellpadding="0" cellspacing="0" border="0">
<tr>
<th>111</th>
<td>222</td>
</tr>
<tr>
<th>111</th>
<td>222</td>
</tr>
</table>
7. 光标大小：
http://hi.baidu.com/jiuyuefenglin/item/dee35b080366f11cebfe3862
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}
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

3. search占位
http://www.qianduan.net/search-box-style-custom-webkit.html
::-webkit-input-placeholder {}
::-moz-input-placeholder {}
input:focus::-webkit-input-placeholder { color: transparent; }
-webkit-appearance:none; google边框去除
input[type="search"]{-webkit-appearance:textfield;} // 去除chrome默认样式
