CSS3 Borders

用CSS3,你可以创建圆角边框,添加阴影框,并作为边界的形象而不使用设计程序,如Photoshop。

在本章中,您将了解以下的边框属性:

  • border-radius

  • box-shadow

  • border-image

浏览器支持

Internet Explorer 9+ 支持 border-radius 和 box-shadow.

Firefox, Chrome, 和 Safari 支持所有最新的 border 属性.

注意: 前缀是-webkit-的Safari支持阴影边框。

前缀是-o-的Opera支持边框图像。

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:

CSS3中的box-shadow属性被用来添加阴影:

CSS3边界图片

有了CSS3的border-image属性,你可以使用图像创建一个边框:

border-image属性允许你指定一个图片作为边框! 用于创建上文边框的原始图像:

在div中使用图片创建边框:

在div中使用图片创建边框div{border-image:url(border.png) 30 30 round;-webkit-border-image:url(border.png) 30 30 round; /* Safari 5 and older */-o-border-image:url(border.png) 30 30 round; /* Opera */}
