你可能用得到的9段CSS代码
一、opacity兼容
.transparent {
filter: alpha(opacity=50);/* internet explorer */
-khtml-opacity: 0.5; /* khtml, old safari */
-moz-opacity: 0.5; /* mozilla, netscape */
opacity: 0.5; /* fx, safari, opera */
}
二、个性化圆角
#container {
-webkit-border-top-left-radius: 4px;
-webkit-border-top-rightright-radius: 3px;
-webkit-border-bottom-rightright-radius: 6px;
-webkit-border-bottom-left-radius: 10px;
-moz-border-radius-topleft: 4px;
-moz-border-radius-topright: 3px;
-moz-border-radius-bottomright: 6px;
-moz-border-radius-bottomleft: 10px;
}
三、隐藏Logo上的H1文本
h1 {
text-indent: -9999px;
margin: 0 auto;
width: 320px;
height: 85px;
background: transparent url("images/logo.png") no-repeat scroll;
}
四、为图片创建拍立得效果边框
img.polaroid {
background:#000;
border:solid #fff;
border-width:6px 6px 20px 6px;
box-shadow:1px 1px 5px #333;
-webkit-box-shadow:1px 1px 5px #333;
-moz-box-shadow:1px 1px 5px #333;
height:200px;
width:200px;
}
五、全屏背景固定效果
html {
background: url('images/bg.jpg') no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
六、内容垂直集中
.container {
min-height: 6.5em;
display: table-cell;
vertical-align: middle;
}
七、创建缝合效果
p {
position:relative;
z-index:1;
padding: 10px;
margin: 10px;
font-size: 21px;
line-height: 1.3em;
color: #fff;
background: #ff0030;
-webkit-box-shadow: 0 0 0 4px #ff0030, 2px 1px 4px 4px rgba
(10,10,0,.5);
-moz-box-shadow: 0 0 0 4px #ff0030, 2px 1px 4px 4px rgba(10,10,0,.5);
box-shadow: 0 0 0 4px #ff0030, 2px 1px 6px 4px rgba(10,10,0,.5);
-webkit-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
}
p:before {
content: "";
position: absolute;
z-index: -1;
top: 3px;
bottombottom: 3px;
left :3px;
rightright: 3px;
border: 2px dashed #fff;
}
p a {
color: #fff;
text-decoration:none;
}
p a:hover, p a:focus, p a:active {
text-decoration:underline;
}
八、经典的CSS Clearfix
.clearfix:after { content: "."; display: block; clear: both; visibility: hidden; line-height: 0; height: 0; }
.clearfix { display: inline-block; }
html[xmlns] .clearfix { display: block; }
* html .clearfix { height: 1%; }
九、垂直滚动条
这段代码将确保你的HTML元素总是稍微高于浏览器滚动条所停留的位置。
html { height: 101% }
