CSS3 圆角
在CSS2中添加圆角棘手。我们不得不在每个角落使用不同的图像。
在CSS3中,很容易创建圆角。
在CSS3中border-radius属性被用于创建圆角:
div
{
border:2px solid;
border-radius:25px;
}
实例:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>W3Cschool教程(w3cschool.cn)</title>
<style>
div
{
border:2px solid #a1a1a1;
padding:10px 40px;
background:#dddddd;
width:300px;
border-radius:40px;
}
</style>
</head>
<body> <div>border-radius</div> </body>
</html>
CSS3盒阴影
CSS3中的box-shadow属性被用来添加阴影:
div
{
box-shadow: 10px 10px 5px #888888;
}
实例:
