css 填坑常用代码分享

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。

因为提交比较麻烦，后来转置github：https://github.com/jsfront/src/blob/master/css.md

一. css 2.x code

1. 文字换行

/*强制不换行*/

white-space:nowrap;

/*自动换行*/

word-wrap: break-word;

textarea{ font-size:13px; resize:none;}

http://www.tuicool.com/articles/EZ777n

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:; }

* 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

.clearfix:after{visibility:hidden;display:block;font-size:;content:" ";clear:both;height:;}

.clearfix{display:inline-block;}

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：

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

16进制的转换

透明兼容

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

background: linear-gradient(to bottom, #bde25e 2%,#8bb31d 100%); /* W3C */

filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#bde25e', endColorstr='#8bb31d',GradientType=0 ); /* IE6-9 */

 @media screen and (max-width:1220px) and (min-width:1151px) {
