【CSS3】background-origin和background-clip的区别_html/css_WEB-ITnose

Jun 21, 2016 am 09:01 AM

background-clip 与 background-origin是css3中引入的两个跟元素背景相关的属性,它们有相同的可选值,即border、padding、content三种,而且这两个属性表示的都是元素背景与元素边框、补白(padding)和内容区域之间的某种关系。

虽然两者看上去实现的效果差不多,但是他们两个的原理是不同的。background-origin定义的是背景位置(background-position)的起始点;而background-clip是对背景(图片和背景色)的切割。

1.background-origin

我们来看一下例子:

我们来看一下style样式:

 .bg{            width: 100px;            height: 100px;            padding:50px;            border: 10px dashed #000000;            background: #ffff00 url('pic1.gif') no-repeat;            margin-top: 10px;            display: inline-block;        }        .bg_origin_border{            background-origin: border-box;            /*background-position: 10px 10px;*/        }        .bg_origin_padding{            background-origin: padding-box;            /*background-position: 10px 10px;*/        }        .bg_origin_content{            background-origin: content-box;            /*background-position: 10px 10px;*/        }
Copy after login

下面我们把注释打开,来进一步验证backgroung-origin。

2.backgroung-clip

我们还是直接来看例子:

样式:

 .bg_clip_border{            background-clip: border-box;            /*background-position: -10px -10px;*/        }        .bg_clip_content{            background-clip: content-box;            /*background-position: -10px -10px;*/        }        .bg_clip_padding{            background-clip: padding-box;            /*background-position: -10px -10px;*/        }
Copy after login

我们接着把注释去掉:

这就印证了background-clip只是将背景和背景色粗暴的裁剪。
