实用的60个CSS代码片段

1、垂直对齐

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

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

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

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;
}

效果演示

4、创建跨浏览器的图像灰度

<svg xmlns="http://www.w3.org/2000/svg">
    <filter id="grayscale">
        <feColorMatrix type="matrix" values="0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0"/>
    </filter>
</svg>

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

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;
}

效果演示：

6、CSS：表格列宽自适用

td {
    white-space: nowrap;
}

7、只在一边或两边显示盒子阴影

     padding: 0px;"> #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;
}

8、包裹长文本

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

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

10、用CSS动画实现省略号动画

.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;
    }
}
