css边框的三个属性

border:

用法：.box{ border:border-width||border-style||border-color;}(第三个颜色使可选的)

 

 

css3中可以创建圆角边框，添加阴影框，并作为边框的形象而不使用设计程序

  1. border-radius:

用法 ：.box{ border-radius:25px;}

  1. border-shadow:

用法 ：.box{ box-shadow:10px 10px 5px #888888;}

第一个参数是X轴偏移量，第二个参数是Y轴偏移量，第三个是阴影的尺寸，第四个是颜色

  1. border-image:

用法 ：.box{ border- image:url() 30 30 round;

         -webkit-border-image:url() 30 30 round;/*Safari and  older*/

         -o-border-image:url() 30 30 round;/*Opera*/

}
