60個有用CSS程式碼片段

1、垂直對齊

如果你用CSS，則你會有困惑：我該怎麼垂直對齊容器中的元素？現在，利用CSS3的Transform，可以很優雅的解決這個困惑：

.verticalcenter{

position: relative;

top: 50%;

-webkit-transform: translateY(-50%);

-o-transform: translateY(-50%);

transform: translateY(-50%);

}

(ps:【譯】如何實現CSS居中？–CSS居中常用方法) 使用這個技巧，從單行文字、段落到box，都會垂直對齊。目前瀏覽器對Transform的支援是需要關注的，Chrome 4, Opera 10, Safari 3, Firefox 3, and Internet Explorer 9.均支援該屬性。

2、伸展一個元素到視窗高度

在具體場景中，你可能想要將一個元素伸展到視窗高度，基本元素的調整隻能調整容器的大小,因此要使一個元素伸展到視窗高度，我們需要伸展頂層元素：html和body:

html,

body {

height: 100%;

}

然後將100%應用到任何元素的高：

div {

height: 100%;

}

3、基於檔案格式使用不同的樣式

為了更容易知道連結的目標，有時你想讓一些連結看起來和其它的不同。下面的片段在文字連結前新增一個圖示，對不同的資源使用不同的圖示或圖片：

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;

}

看起來是這樣的:http://jsfiddle.net/agusesetiyono/3sL1r0mw/light/

4、建立跨瀏覽器的影象灰度

灰度有時看起來簡約和優雅，能為網站呈現更深層次的色調。在示例中，我們將對一個SVG影象新增灰度過濾：

<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>

為了跨瀏覽器，會用到filter屬性：

img {

filter: url(filters.svg#grayscale); /* Firefox 3.5+ */

filter: gray; /* IE6-9 */

-webkit-filter: grayscale(1); /* Google Chrome, Safari 6+ & Opera 15+ */

}

5、背景漸變動畫

CSS中最具誘惑的一個功能是能新增動畫效果，除了漸變，你可以給背景色、透明度、元素大小新增動畫。目前，你不能為漸變新增動畫，但下面的程式碼可能有幫助。它通過改變背景位置，讓它看起來有動畫效果。

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;

}

效果在這裡：http://jsfiddle.net/agusesetiyono/gw46dk27/1/light/

6、CSS：表格列寬自適用

對於表格，當談到調整列寬時，是比較痛苦的。然後，這裡有一個可以使用的技巧：給td元素新增 white-space: nowrap;能讓文字正確的換行

td {

white-space: nowrap;

}

檢視效果：http://jsfiddle.net/agusesetiyono/1uotj8wv/3/light/

7、只在一邊或兩邊顯示盒子陰影

如果你要一個盒陰影，試試這個技巧，能為任一邊新增陰影。為了實現這個，首先定義一個有具體寬高的盒子，然後正確定位:after偽類。實現底邊陰影的程式碼如下：

.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、包裹長文字

如果你碰到一個比自身容器長的文字，這個技巧對你很有用。在這個示例中，預設時，不管容器的寬度，文字都將水平填充。

long text

簡單的CSS程式碼就能在容器中調整文字：

pre {

white-space: pre-line;

word-wrap: break-word;

}

效果看起來如下：

effect

9、製造模糊文字

想要讓文字模糊？可以使用color透明和text-shadow實現。

.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動畫實現省略號動畫

這個片段將幫助你製造一個ellipsis的動畫，對於簡單的載入狀態是很有用的，而不用去使用gif影象。

.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、樣式重置

font: inherit;

vertical-align: baseline;

outline: none;

-webkit-box-sizing: border-box;

-moz-box-sizing: border-box;

box-sizing: border-box;

}

html { height: 101%; }

body { font-size: 62.5%; line-height: 1; font-family: Arial, Tahoma, sans-serif; }

 

article, aside, details, figcaption, figure, footer, header, hgroup, menu, nav, section { display: block; }

ol, ul { list-style: none; }

 

blockquote, q { quotes: none; }

blockquote:before, blockquote:after, q:before, q:after { content: ''; content: none; }

strong { font-weight: bold; }

 

table { border-collapse: collapse; border-spacing: 0; }

12、典型的CSS清除浮動

* html .clearfix { height: 1%; }

13、新版清除浮動（2011）

.clearfix:after { clear: both; }

 

/* IE 6/7 */

.clearfix { zoom: 1; }

14、跨瀏覽器的透明

.transparent {

filter: alpha(opacity=50); /* internet explorer */

opacity: 0.5; /* fx, safari, opera */

}

15、CSS引用模板

}

blockquote:before {

color: #ccc;

content: open-quote;
