实用的60个CSS代码片段

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：

<code class="css"><span class="hljs-class">.verticalcenter<span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">position:<span class="hljs-value"> relative;
    <span class="hljs-rule"><span class="hljs-attribute">top:<span class="hljs-value"> <span class="hljs-number">50%;
    <span class="hljs-rule"><span class="hljs-attribute">-webkit-transform:<span class="hljs-value"> <span class="hljs-function">translateY(-<span class="hljs-number">50%);
    <span class="hljs-rule"><span class="hljs-attribute">-o-transform:<span class="hljs-value"> <span class="hljs-function">translateY(-<span class="hljs-number">50%);
    <span class="hljs-rule"><span class="hljs-attribute">transform:<span class="hljs-value"> <span class="hljs-function">translateY(-<span class="hljs-number">50%);
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

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:

<code class="css"><span class="hljs-tag">html, 
<span class="hljs-tag">body <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">100%;
}</span></span></span></span></span></span></span></code>

然后将100%应用到任何元素的高

<code class="css"><span class="hljs-tag">div <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">100%;
}</span></span></span></span></span></span></code>

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：

<code class="css"><span class="hljs-tag">a<span class="hljs-attr_selector">[href^="http://"]<span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">padding-right:<span class="hljs-value"> <span class="hljs-number">20px;
    <span class="hljs-rule"><span class="hljs-attribute">background:<span class="hljs-value"> <span class="hljs-function">url(external.gif) no-repeat center right;
}
<span class="hljs-comment">/* emails */
<span class="hljs-tag">a<span class="hljs-attr_selector">[href^="mailto:"]<span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">padding-right:<span class="hljs-value"> <span class="hljs-number">20px;
    <span class="hljs-rule"><span class="hljs-attribute">background:<span class="hljs-value"> <span class="hljs-function">url(email.png) no-repeat center right;
}

<span class="hljs-comment">/* pdfs */
<span class="hljs-tag">a<span class="hljs-attr_selector">[href$=".pdf"]<span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">padding-right:<span class="hljs-value"> <span class="hljs-number">20px;
    <span class="hljs-rule"><span class="hljs-attribute">background:<span class="hljs-value"> <span class="hljs-function">url(pdf.png) no-repeat center right;
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

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：

<code class="xml"><span class="hljs-tag"><<span class="hljs-title">svg <span class="hljs-attribute">xmlns=<span class="hljs-value">"http://www.w3.org/2000/svg">
    <span class="hljs-tag"><<span class="hljs-title">filter <span class="hljs-attribute">id=<span class="hljs-value">"grayscale">
        <span class="hljs-tag"><<span class="hljs-title">feColorMatrix <span class="hljs-attribute">type=<span class="hljs-value">"matrix" <span class="hljs-attribute">values=<span class="hljs-value">"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"/>
    <span class="hljs-tag"></<span class="hljs-title">filter>
<span class="hljs-tag"></<span class="hljs-title">svg></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

为了跨浏览器，会用到filter属性：

<code class="css"><span class="hljs-tag">img <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">filter:<span class="hljs-value"> <span class="hljs-function">url(filters.svg#grayscale); <span class="hljs-comment">/* Firefox 3.5+ */
    <span class="hljs-rule"><span class="hljs-attribute">filter:<span class="hljs-value"> gray; <span class="hljs-comment">/* IE6-9 */
    <span class="hljs-rule"><span class="hljs-attribute">-webkit-filter:<span class="hljs-value"> <span class="hljs-function">grayscale(<span class="hljs-number">1); <span class="hljs-comment">/* Google Chrome, Safari 6+ & Opera 15+ */
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

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。

<code class="css"><span class="hljs-tag">button <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">background-image:<span class="hljs-value"> <span class="hljs-function">linear-gradient(<span class="hljs-hexcolor">#5187c4, <span class="hljs-hexcolor">#1c2f45);
    <span class="hljs-rule"><span class="hljs-attribute">background-size:<span class="hljs-value"> auto <span class="hljs-number">200%;
    <span class="hljs-rule"><span class="hljs-attribute">background-position:<span class="hljs-value"> <span class="hljs-number">0 <span class="hljs-number">100%;
    <span class="hljs-rule"><span class="hljs-attribute">transition:<span class="hljs-value"> background-position <span class="hljs-number">0.5s;
}    
<span class="hljs-rule"><span class="hljs-attribute">button:<span class="hljs-value">hover {
    background-position: <span class="hljs-number">0 <span class="hljs-number">0;
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

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

<code class="css"><span class="hljs-tag">td <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">white-space:<span class="hljs-value"> nowrap;
}</span></span></span></span></span></code>

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

<code class="css"><span class="hljs-class">.box-shadow <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">background-color:<span class="hljs-value"> <span class="hljs-hexcolor">#FF8020;
    <span class="hljs-rule"><span class="hljs-attribute">width:<span class="hljs-value"> <span class="hljs-number">160px;
    <span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">90px;
    <span class="hljs-rule"><span class="hljs-attribute">margin-top:<span class="hljs-value"> -<span class="hljs-number">45px;
    <span class="hljs-rule"><span class="hljs-attribute">margin-left:<span class="hljs-value"> -<span class="hljs-number">80px;
    <span class="hljs-rule"><span class="hljs-attribute">position:<span class="hljs-value"> absolute;
    <span class="hljs-rule"><span class="hljs-attribute">top:<span class="hljs-value"> <span class="hljs-number">50%;
    <span class="hljs-rule"><span class="hljs-attribute">left:<span class="hljs-value"> <span class="hljs-number">50%;
}
<span class="hljs-rule"><span class="hljs-attribute">.box-shadow:<span class="hljs-value">after {
    content: <span class="hljs-string">"";
    <span class="hljs-rule"><span class="hljs-attribute">width:<span class="hljs-value"> <span class="hljs-number">150px;
    <span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">1px;
    <span class="hljs-rule"><span class="hljs-attribute">margin-top:<span class="hljs-value"> <span class="hljs-number">88px;
    <span class="hljs-rule"><span class="hljs-attribute">margin-left:<span class="hljs-value"> -<span class="hljs-number">75px;
    <span class="hljs-rule"><span class="hljs-attribute">display:<span class="hljs-value"> block;
    <span class="hljs-rule"><span class="hljs-attribute">position:<span class="hljs-value"> absolute;
    <span class="hljs-rule"><span class="hljs-attribute">left:<span class="hljs-value"> <span class="hljs-number">50%;
    <span class="hljs-rule"><span class="hljs-attribute">z-index:<span class="hljs-value"> -<span class="hljs-number">1;
    <span class="hljs-rule"><span class="hljs-attribute">-webkit-box-shadow:<span class="hljs-value"> <span class="hljs-number">0px <span class="hljs-number">0px <span class="hljs-number">8px <span class="hljs-number">2px <span class="hljs-hexcolor">#000000;
       <span class="hljs-rule"><span class="hljs-attribute">-moz-box-shadow:<span class="hljs-value"> <span class="hljs-number">0px <span class="hljs-number">0px <span class="hljs-number">8px <span class="hljs-number">2px <span class="hljs-hexcolor">#000000;
            <span class="hljs-rule"><span class="hljs-attribute">box-shadow:<span class="hljs-value"> <span class="hljs-number">0px <span class="hljs-number">0px <span class="hljs-number">8px <span class="hljs-number">2px <span class="hljs-hexcolor">#000000;
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

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：

<code class="css"><span class="hljs-tag">pre <span class="hljs-rules">{
    <span class="hljs-rule"><span class="hljs-attribute">white-space:<span class="hljs-value"> pre-line;
    <span class="hljs-rule"><span class="hljs-attribute">word-wrap:<span class="hljs-value"> break-word;
}</span></span></span></span></span></span></span></span></code>

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

<code class="css"><span class="hljs-class">.blurry-text <span class="hljs-rules">{
   <span class="hljs-rule"><span class="hljs-attribute">color:<span class="hljs-value"> transparent;
   <span class="hljs-rule"><span class="hljs-attribute">text-shadow:<span class="hljs-value"> <span class="hljs-number">0 <span class="hljs-number">0 <span class="hljs-number">5px <span class="hljs-function">rgba(<span class="hljs-number">0,<span class="hljs-number">0,<span class="hljs-number">0,<span class="hljs-number">0.5);
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

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。

<code class="css"><span class="hljs-rule"><span class="hljs-attribute">.loading:<span class="hljs-value">after {
    overflow: hidden;
    <span class="hljs-rule"><span class="hljs-attribute">display:<span class="hljs-value"> inline-block;
    <span class="hljs-rule"><span class="hljs-attribute">vertical-align:<span class="hljs-value"> bottom;
    <span class="hljs-rule"><span class="hljs-attribute">animation:<span class="hljs-value"> ellipsis <span class="hljs-number">2s infinite;
    <span class="hljs-rule"><span class="hljs-attribute">content:<span class="hljs-value"> <span class="hljs-string">"\2026"; <span class="hljs-comment">/* ascii code for the ellipsis character */
}
<span class="hljs-at_rule">@<span class="hljs-keyword">keyframes ellipsis {
    <span class="hljs-tag">from <span class="hljs-rules">{
        <span class="hljs-rule"><span class="hljs-attribute">width:<span class="hljs-value"> <span class="hljs-number">2px;
    }
    <span class="hljs-tag">to <span class="hljs-rules">{
        <span class="hljs-rule"><span class="hljs-attribute">width:<span class="hljs-value"> <span class="hljs-number">15px;
    }
}</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>
