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&reg;">  <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。
