前几天偶然间看到了[Adham Dannaway][]的网站，首页的效果狠感人，让人耐不住冲动想研究研究，这不，昨天把它抠了出来，分享给大家。为了简化问题，阉割了浏览器检测和响应式布局，sorry，感兴趣的朋友可以自行找[Adham Dannaway][]研究。

大家可以看[demo][]，或是[下载][Link 1]。

下面来看看具体的实现方法。

# 文档结构 #

主要效果的html文档部分如下，主要分为两个部分，文字显示，图片动画。div\#designer和div\#coder用来显示文字，img\#face-img用来显示初始的图片，div\#designer-img、div\#designer-bg和div\#coder-img、div\#coder-bg用来实现鼠标移动时的图片切换效果。

<div id="content" class="content clearfix home">
      <section id="section" class="light nopad-t nopad-b">
    	<div id="face" class="face">
    		<a href="http://www.adhamdannaway.com/portfolio">
    			<div id="designer" class="designer">
    				<div id="designer-desc" class="description">
    					<h1>designer</h1>
    					<p>User Interface Designer with a passion for designing 
    	beautiful and functional user experiences. Minimalist who believes that less is more.</p>
    				</div>
    			</div>
    		</a>
    		<a href="http://www.adhamdannaway.com/about">
    			<div id="coder" class="coder">
    				<div id="coder-desc" class="description">
    					<h1><coder></h1>
    					<p>Front End Developer who focuses on writing clean, elegant and efficient code. Love HTML5, CSS3, WordPress  and a touch of jQuery.</p>
    				</div>
    			</div>
    		</a>
    		<div id="designer-img" class="designer-img"></div>
    		<div id="coder-img" class="coder-img"></div>
    		<div id="designer-bg" class="designer-bg"></div>
    		<div id="coder-bg" class="coder-bg"></div>
    	</div>
      </section>
    </div>

加入css和js，这个是关键。

# css布局 #

css实现布局

.face {
    	width: 1040px;
