            在上面的段落中，文本的第一个字母包含在一个 span 元素中。这个 span 元素的宽度是当前字体尺寸的 0.7 倍。span 元素的字体尺寸是 400%，行高是 80%。span 中的字母字体是 "Algerian"        
    

06创建水平菜单

在上面的例子中，我们把 ul 元素和 a 元素浮向左浮动。li 元素显示为行内元素（元素前后没有换行）。这样就可以使列表排列成一行。ul 元素的宽度是 100%，列表中的每个超链接的宽度是 7em（当前字体尺寸的 7 倍）。我们添加了颜色和边框，以使其更漂亮。

07创建无表格的首页

    
            
                
浣溪沙·一曲新词酒一杯
            
            
                
听一支新曲喝一杯美酒，还是去年的天气旧日的亭台，西落的夕阳何时再回来？
            
            
                
浣溪沙·一曲新词酒一杯
                
一曲新词酒一杯，去年天气旧亭台。夕阳西下几时回？
                
无可奈何花落去，似曾相识燕归来。小园香径独徘徊。
            
            
此词虽含伤春惜时之意，却实为感慨抒怀之情。
        
    

08定位：相对定位

    
我是位于正常位置的标题,相对定位会按照我的原始位置对我进行移动
        
样式 "left:-20px" 从我的左侧位置减去 20 像素
        
样式 "left:50px" 向我的左侧位置增加 50 像素
    

09定位：绝对定位

    
我是带有绝对定位的标题
        
通过绝对定位，元素可以放置到页面上的任何位置。下面的标题距离页面左侧 100px，距离页面顶部 150px。
    

10定位：固定定位

    
一些文本。
        
更多的文本。
