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%);
}

使用這個技巧，從單行文本、段落到box，都會垂直對齊。目前瀏覽器對Transform的支持是需要關注的，

Chrome 4, Opera 10, Safari 3, Firefox 3, and Internet Explorer 9均支持該屬性。

伸展一個元素到窗口高度

在具體場景中，你可能想要將一個元素伸展到窗口高度，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窗口高度，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%;
}

基於文件格式使用不同的樣式

爲了更容易知道鏈接的目標，有時你想讓一些鏈接看起來和其它的不同。下面的片段在文本鏈接前添加一個圖標，對不同的資源使用不同的圖標或圖片：

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;
}

創建跨瀏覽器的圖像灰度

灰度有時看起來簡約和優雅，能爲網站呈現更深層次的色調。在示例中，我們將對一個SVG圖像添加灰度過濾：

<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>

爲了跨瀏覽器，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+ */
}

背景漸變動畫

CSS中最具誘惑的一個功能是能添加動畫效果，除了漸變，你可以給背景色、透明度、元素大小添加動畫。目前，你不能爲漸變添加動畫，但下面的代碼可能有幫助。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;
}

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，這裏有一個可以使用的技巧：給td元素添加white-space: nowrap;能讓文本正確的換行

td {
    white-space: nowrap;
}

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，能爲任一邊添加陰影。爲了實現這個，首先定義一個有具體寬高的盒子，然後正確定位:after僞類。實現底邊陰影的代碼如下:

.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;
}

包裹長文本

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

簡單的CSS代碼就能在容器中調整文本：

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

效果看起來如下：

製造模糊文本

想要讓文本模糊？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);
}

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，對於簡單的加載狀態是很有用的，而不用去使用gif圖像。

.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;
    }
}
