CSS常用样式整理

元素边框显示圆角：-moz-border-radius适用于火狐浏览器，-webkit-border-radius适用于Safari和Chrome两种浏览器。

浏览器渐变背景颜色：

FILTER: progid:DXImageTransform.Microsoft.Gradient(gradientType=0,startColorStr=#b8c4cb,endColorStr=#f6f6f8); /*IE789*/
background:-moz-linear-gradient(top,#b8c4cb,#f6f6f8);/*火狐*/
background:-webkit-gradient(linear, 0% 0%, 0% 100%,from(#b8c4cb), to(#f6f6f8));/*谷歌*/
background: -moz-linear-gradient(top, #000000 0%, #ffffff 100%);/*火狐*/
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#000000), color-stop(100%,#ffffff));/*谷歌*/
background: -webkit-linear-gradient(top, #000000 0%,#ffffff 100%);
background: -o-linear-gradient(top, #000000 0%,#ffffff 100%);/*IE1011*/
background: -ms-linear-gradient(top, #000000 0%,#ffffff 100%);/*IE1011*/
background: linear-gradient(to bottom, #000000 0%,#ffffff 100%);/*IE1011*/

IE6支持fixed

#top{ position:fixed; _position:absolute; bottom:0; right:20px; _bottom:auto; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight-(parseInt(this.currentStyle.marginTop,10)||0)-(parseInt(this.currentStyle.marginBottom,10)||0))); }

right 跟 left 属性可以用绝对定位的办法解决，而 top 跟 bottom 就需要用上面的表达式来实现。其中在 _position:absolute; 中的 _ 符号只有 IE6 才能识别

input皮肤设置常用样式

input[type=text]
{
    border:1px solid #8C8C8C;   
   }
input[type=text]:hover
{
    border:1px solid #5E5E5E;   
   }
   input[type=text]:focus 
{
    border:1px solid #247CC0;   
   }

 为元素设置边框阴影

-moz-box-shadow: 2px 2px 10px #909090;/*firefox*/
-webkit-box-shadow: 2px 2px 10px #909090;/*safari或chrome*/
box-shadow:2px 2px 10px #909090;/*opera或ie9*/
box-shadow:inset 0 2px 5px #e3e3e3;/*文本框内阴影*/

第一个参数是x轴阴影段长度 第二个参数是y轴阴影段长度 第三个参数是往四周阴影段长度 第四个参数是阴影段颜色

页面空间元素显示圆角样式

border-radius: 3px 3px 3px 3px;

文本框内阴影设置

box-shadow:inset 0 2px 5px #e3e3e3; /*文本框内阴影*/

 input常用样式

  input[type=text],input[type=password],select,textarea{ border:1px solid #8C8C8C; box-shadow:inset 0 2px 5px #e3e3e3; border-radius: 3px 3px 3px 3px;}
  input[type=text]:hover,input[type=password]:hover,select:hover,textarea:hover{border:1px solid #5E5E5E;}
  input[type=text]:focus,input[type=password]:focus,select:focus,textarea:focus{border:1px solid #247CC0; -moz-box-shadow: 2px 2px 10px #909090;-webkit-box-shadow: 2px 2px 10px #909090;box-shadow:2px 2px 10px #909090;}

兼容IE样式

  input[type=text],input[type=password],select,textarea 
        {
            border:1px solid #8C8C8C;            
            padding-left:10px;
            line-height:25px; 
            height:25px; 
            width:300px;
            box-shadow:inset 0px 2px 5px #e3e3e3;
            -webkit-box-shadow:inset 0px 2px 5px #e3e3e3;
            -moz-box-shadow: inset 0px 2px 5px #e3e3e3;
            filter:shadow(color=#666666, direction=135, strength=1) progid:DXImageTransform.Microsoft.Blur(pixelRadius=2, direction=135);
            border-radius: 3px;
            behavior: url(../../App_Css/border-radius.htc);
         }
    input[type=text]:hover,input[type=password]:hover,select:hover,textarea:hover{border:1px solid #5E5E5E;}
    input[type=text]:focus,input[type=password]:focus,select:focus,textarea:focus
    {
        border:1px solid #247CC0;
        -moz-box-shadow: 2px 2px 10px #909090;
        -webkit-box-shadow: 2px 2px 10px #909090;
        box-shadow:2px 2px 10px #909090;
        filter:shadow(color=#666666, direction=135, strength=1) progid:DXImageTransform.Microsoft.Blur(pixelRadius=2, direction=135);
    }

IE678对于圆角设置常常不支持，借助ie-css3.htc实现兼容。赋值一下代码贴入新建ie-css3.htc文件，页面引用 behavior: url(../../App_Css/border-radius.htc);

Changes by Nick Fetchak:
- IE8 standards mode compatibility
- VML elements now positioned behind original box rather than inside of it - should be less prone to breakage
- Added partial support for 'box-shadow' style
- Checks for VML support before doing anything
- Updates VML element size and position via timer and also via window resize event
- lots of other small things
