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);
