html实现圆角矩形
问题：如何通过div+css以及定位来实现圆角矩形？
解决方法概述：
内容：首先在
标签内部里添加一个大层（大层用来固定整体大框架），然后大层内包含四个小层（四个小层里分别放四个圆角（事先用ps做好椭圆形形状，然后用切片工具切图 ））样式：在
标签内部设置的css要有的属性：1.position：relative；
2.宽和高;
3背景颜色;
4.边框线（用来调整四个原角的相对位置，调整好后可以将边框线设置删除）
在设置小层的css时，每个层里都要有的属性有：
1.position：absolute；
2.宽和高；
3.方向属性（left，right，bottom,top）
4.background：url（""）no-repeat;(引入各个方向的圆角图片)
以下是我实现圆角矩形的代码：
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="Generator" content="EditPlus®">
<meta name="Author" content="">
<meta name="Keywords" content="">
<meta name="Description" content="">
<title>圆角制作</title>
<style type=text/css>
#p
{
position:relative;
width:400px;
height:200px;
background:black;
margin:auto;
}
#plefttop
{
position:absolute;
width:50px;
height:50px;
background:url("images/11.jpg") no-repeat;
}
#prighttop
{
position:absolute;
width:50px;
height:50px;
right:-9px;
top:0px;
background:url("images/22.jpg") no-repeat;
}
#pleftbottom
{
position:absolute;
width:50px;
height:50px;
left:0px;
bottom:-14px;
background:url("images/33.jpg") no-repeat;
}
#prightbottom
{
position:absolute;
width:50px;
height:50px;
right:-9px;
bottom:-14px;
background:url("images/44.jpg") no-repeat;
}
</style>
</head>
<body>
<div id=p>
<div id=plefttop></div>
<div id=prighttop></div>
<div id=pleftbottom></div>
<div id=prightbottom></div>
</div>
</body>
</html>
注意：我的代码里用的css样式是内联式，CSS样式有三种：内联式，嵌入式，外部式。
