【译】60个有用CSS代码片段_html/css_WEB-ITnose

1、垂直对齐

如果你用CSS，则你会有困惑：我该怎么垂直对齐容器中的元素？现在，利用CSS3的Transform，可以很优雅的解决这个困惑：

.verticalcenter{    position: relative;    top: 50%;    -webkit-transform: translateY(-50%);    -o-transform: translateY(-50%);    transform: translateY(-50%);}

(ps:【译】如何实现CSS居中？?CSS居中常用方法)
使用这个技巧，从单行文本、段落到box，都会垂直对齐。目前浏览器对Transform的支持是需要关注的，Chrome 4, Opera 10, Safari 3, Firefox 3, and Internet Explorer 9.均支持该属性。

2、伸展一个元素到窗口高度

在具体场景中，你可能想要将一个元素伸展到窗口高度，基本元素的调整只能调整容器的大小,因此要使一个元素伸展到窗口高度，我们需要伸展顶层元素：html和body:

html, body {    height: 100%;}

然后将100%应用到任何元素的高：

div {    height: 100%;}

3、基于文件格式使用不同的样式

为了更容易知道链接的目标，有时你想让一些链接看起来和其它的不同。下面的片段在文本链接前添加一个图标，对不同的资源使用不同的图标或图片：

a[href^="http://"]{    padding-right: 20px;    background: url(external.gif) no-repeat center right;}/* emails */a[href^="mailto:"]{    padding-right: 20px;    background: url(email.png) no-repeat center right;}/* pdfs */a[href$=".pdf"]{    padding-right: 20px;    background: url(pdf.png) no-repeat center right;}

看起来是这样的:http://jsfiddle.net/agusesetiyono/3sL1r0mw/light/

4、创建跨浏览器的图像灰度

灰度有时看起来简约和优雅，能为网站呈现更深层次的色调。在示例中，我们将对一个SVG图像添加灰度过滤：

为了跨浏览器，会用到filter属性：

img {    filter: url(filters.svg#grayscale); /* Firefox 3.5+ */    filter: gray; /* IE6-9 */    -webkit-filter: grayscale(1); /* Google Chrome, Safari 6+ & Opera 15+ */}

5、背景渐变动画

CSS中最具诱惑的一个功能是能添加动画效果，除了渐变，你可以给背景色、透明度、元素大小添加动画。目前，你不能为渐变添加动画，但下面的代码可能有帮助。它通过改变背景位置，让它看起来有动画效果。

button {    background-image: linear-gradient(#5187c4, #1c2f45);    background-size: auto 200%;    background-position: 0 100%;    transition: background-position 0.5s;}    button:hover {    background-position: 0 0;}

效果在这里：http://jsfiddle.net/agusesetiyono/gw46dk27/1/light/

6、CSS：表格列宽自适用

对于表格，当谈到调整列宽时，是比较痛苦的。然后，这里有一个可以使用的技巧：给td元素添加 white-space: nowrap;能让文本正确的换行

td {    white-space: nowrap;}

查看效果：http://jsfiddle.net/agusesetiyono/1uotj8wv/3/light/

7、只在一边或两边显示盒子阴影

如果你要一个盒阴影，试试这个技巧，能为任一边添加阴影。为了实现这个，首先定义一个有具体宽高的盒子，然后正确定位:after伪类。实现底边阴影的代码如下：

.box-shadow {    background-color: #FF8020;    width: 160px;    height: 90px;    margin-top: -45px;    margin-left: -80px;    position: absolute;    top: 50%;    left: 50%;}.box-shadow:after {    content: "";    width: 150px;    height: 1px;    margin-top: 88px;    margin-left: -75px;    display: block;    position: absolute;    left: 50%;    z-index: -1;    -webkit-box-shadow: 0px 0px 8px 2px #000000;       -moz-box-shadow: 0px 0px 8px 2px #000000;            box-shadow: 0px 0px 8px 2px #000000;}

效果：http://jsfiddle.net/agusesetiyono/1kwhsfvo/light/

8、包裹长文本

如果你碰到一个比自身容器长的文本，这个技巧对你很有用。在这个示例中，默认时，不管容器的宽度，文本都将水平填充。

简单的CSS代码就能在容器中调整文本：

pre {    white-space: pre-line;    word-wrap: break-word;}

效果看起来如下：

9、制造模糊文本

想要让文本模糊？可以使用color透明和text-shadow实现。

.blurry-text {   color: transparent;   text-shadow: 0 0 5px rgba(0,0,0,0.5);}

demo:http://jsfiddle.net/agusesetiyono/n5uh4s0j/light/

10、用CSS动画实现省略号动画

这个片段将帮助你制造一个ellipsis的动画，对于简单的加载状态是很有用的，而不用去使用gif图像。

.loading:after {    overflow: hidden;    display: inline-block;    vertical-align: bottom;    animation: ellipsis 2s infinite;    content: "\2026"; /* ascii code for the ellipsis character */}@keyframes ellipsis {    from {        width: 2px;    }    to {        width: 15px;    }}

效果：http://jsfiddle.net/agusesetiyono/MDzsR/69/light/

11、样式重置

12、典型的CSS清除浮动
