CSS垂直居中哪個(gè)方法最好呢?
我最喜歡的是方法三,缺點(diǎn)不多。因?yàn)?content 會(huì)清除浮動(dòng),所以可以在它上面放置別的元素,并且當(dāng)窗口縮放時(shí), 居中的 content 不會(huì)把另外的元素蓋住。看例子。
<div id="top">
<h1>Title</h1>
</div>
<div id="content">
Content Here</div>
#floater {float:left; height:50%; margin-bottom:-120px;}
#top {float:right; width:100%; text-align:center;}
#content {clear:both; height:240px; position:relative;}
現(xiàn)在你知道是怎么回事了,現(xiàn)在我們開始創(chuàng)建一個(gè)簡(jiǎn)單但是有趣的網(wǎng)站。最終的樣子是這樣的:

步驟一 以語(yǔ)義化標(biāo)簽開始是很好的。下面是我們的頁(yè)面構(gòu)成:
#floater/*把 content 置中*/ #contred/*centre 盒*/ #side #logo #nav/*無(wú)序列表*/ #content #bottom/*放置版權(quán)等*/這是我用到的 xhtml 代碼:
A Centred Company <div id="centered"> <div id="side"> <div id="logo"> <strong><span>A</span> Company</strong></div> <ul id="nav"> <li><a href="#">Home</a></li> <li><a href="#">Products</a></li> <li><a href="#">Blog</a></li> <li><a href="#">Contact</a></li> <li><a href="#">About</a></li> </ul> </div> <div id="content"> <h1>Page Title</h1> Holisticly re-engineer value-added outsourcing after process-centric collaboration and idea-sharing. Energistically simplify impactful niche markets via enabled imperatives. Holisticly predominate premium innovation after compelling scenarios. Seamlessly recaptiualize high standards in human capital with leading-edge manufactured products. Distinctively syndicate standards compliant schemas before robust vortals. Uniquely recaptiualize leveraged web-readiness vis-a-vis out-of-the-box information. <h2>Heading 2</h2> Efficiently embrace customized web-readiness rather than customer directed processes. Assertively grow cross-platform imperatives vis-a-vis proactive technologies. Conveniently empower multidisciplinary meta-services without enterprise-wide interfaces. Conveniently streamline competitive strategic theme areas with focused e-markets. Phosfluorescently syndicate world-class communities vis-a-vis value-added markets. Appropriately reinvent holistic services before robust e-services.</div> </div> <div id="bottom"> Copyright notice goes here</div>
