【准备工作】
一、如图示,创建网站框架:
二、reset.css文件参考内容:
[css] view plaincopyprint?/*YUI的CSS Reset
*/
body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, form, fieldset, input, textarea, p, blockquote, th, td
{
padding: 0;
margin: 0;
}
table
{
border-collapse: collapse;
border-spacing: 0;
}
fieldset, img
{
border: 0;
}
address, caption, cite, code, dfn, em, strong, th, var
{
font-weight: normal;
font-style: normal;
}
ol, ul
{
list-style: none;
}
caption, th
{
text-align: left;
}
h1, h2, h3, h4, h5, h6
{
font-weight: normal;
font-size: 100%;
}
q:before, q:after
{
content: '';
}
abbr, acronym
{
border: 0;
}
/*YUI的CSS Reset
*/
body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, form, fieldset, input, textarea, p, blockquote, th, td
{
padding: 0;
margin: 0;
}
table
{
border-collapse: collapse;
border-spacing: 0;
}
fieldset, img
{
border: 0;
}
address, caption, cite, code, dfn, em, strong, th, var
{
font-weight: normal;
font-style: normal;
}
ol, ul
{
list-style: none;
}
caption, th
{
text-align: left;
}
h1, h2, h3, h4, h5, h6
{
font-weight: normal;
font-size: 100%;
}
q:before, q:after
{
content: '';
}
abbr, acronym
{
border: 0;
}
【说明】
据说是YUI的CSS Reset,版本不详,有知道源文件出处的还望不吝赐教。
这个文件,在此处主要起作用的是{padding: 0; margin: 0;},相当于取代了常用设置*{padding: 0; margin: 0;}。
三、引用图片
bg-header.jpg
bg-pattern.jpg
nav.png
【操作步骤】
一、效果
二、HTML
[html]
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link href="css/reset.css" rel="stylesheet" type="text/css" />
<link href="css/layout.css" rel="stylesheet" type="text/css" />
<title>无标题页</title>
</head>
<body>
<div id="header">
<ul id="nav">
<li><a href="#" id="farm">Our Farm</a></li>
<li><a href="#" id="blog">The Blog</a></li>
<li><a href="#" id="shop">Shop</a></li>
<li><a href="#" id="info">Info & Extras</a></li>
<li><a href="#" id="contact">Contact Us</a></li>
</ul>
</div>
</body>
</html>

<li><a href="#" id="info">Info & Extras</a></li>
<li><a href="#" id="contact">Contact Us</a></li>
</ul>
</div>
</body>
</html>【说明】
本实例中,导航栏三个状态是在lay.css文件中的样式中,由背景图片nav.png实现的,列表中的列表项文字并没有显示出来,也许会在不支持样式表的掌上网络设备中显示吧。
三、CSS

【说明】
1、这个样式表的主要技术是设置background-position属性,导航条5个链接3个状态共15个图片都做在了一张高度为3*112=336px的图片nav.png上,通过设置background-position 属性,也就是设置背景图像的起始位置,来截取不同的背景图片的。这些个起始位置是根据大致的计算,经过调整所得。
2、样式a,主要是去除连接文字默认的下划线;
3、样式a:focus,主要是去除点击链接时,由于获得焦点,而在链接图片周围显示的一个虚线方框;
4、a:active的效果,可以在点击链接时,按住鼠标不放,显示出来。
