3.背景
由于博主懒的去找背景的素材,所以运行之后,丑的不堪入目,不过重点没有错误嘛,大家关注代码所对应的效果就好了。

[html] view
plain copy







<html>

<head>

<title>background</title>

<style>

body{

background-color:yellow;

background-image:url(a.png);

background-repeat:repeat;

background-attachment:fixed;

}

h1{

background-color:green;

background-image:url(bb.png);

</head>

<h1>this is header one</h1>

<h2>this is header two</h2>

<p>this is a paragraph </p>

<a href="http://www.baidu.com">aaaaaaaaaaaaaaaaa</a>

</body>

</html>

运行结果:



这张截图有点,看起来乱七八糟的,但是根据代码来找效果,也是很快的。很容易搞明白,每一句代码的意思。url就是自己随便哦添加的路径,大家不必在意。
4.边框(PS:加几句关于鼠标指针的代码)

[html] view
plain copy







<html>

<head>

<title>border</title>

<style>

div{

width:80px;

height:25px;

border-style:solid dotted;

cursor:move;

}

h1{

border-style:solid double dashed inset;

border-top-style:solid;

border-right-style:double;

border-bottom-style:dashed;

border-left-style:inset;

border-width:1px 2px 3px 4px;

/*

设置边框第二种方式:

border-top-width:1px;

border-right-width:2px;

border-bottom-width:3px;

border-left-width:4px;

*/

border-color:red yellow green blue;

cursor:wait;

}

h2{

border:3px solid green;

/*会覆盖上面的border设置*/

border:1px dashed red;

cursor:pointer;

}

</style>

</head>

<body>

<div>

aaaaaa

</div>

<h1>this is header one</h1>

<h2>this is header two</h2>

</body>

</html>

运行结果:



当鼠标移到三个边框上时,鼠标指针会发生相应变化:分别变成移动,等待,还有小手的状态。具体参考<style>标签内的代码。
5.列表

[html] view
plain copy







<html>

<head>

<title>list</title>

<style>

</style>

</head>

<body>

<ul style="list-style-type:none; list-style-image:url(bb.png)">

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

</ul>

<ol style="list-style-type:upper-roman">

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

<li>aaaaaaaaaaaaa</li>

</ol>

</body>

</html>

运行结果:



截图中所显示的两个列表分别是一个无序列表和一个有序列表。
但是在以后的开发中,我们基本不会使用默认的图像,都是自定义列表前面的图像。style="list-style-type:none.这句代码就是将列表前的符号风格设置为空,然后我们就可以自行添加自己需要的图像了。
