问题描述

是否可以在background-image上使用 -webkit-filter:blur();



我试过这个代码,它只是模糊了一切,但背景图像:

  body {
background-image: url('http://www.publicdomainpictures.net/pictures/10000/velka/pebbles-and-sea-11284647414Rbeh.jpg');
background-attachment:fixed;
-webkit-filter:blur(5px);
}

我一直在寻找一段时间,但找不到任何资源描述如何做:不支持在IE7,IE8,IE9中使用此功能。

,IE10,IE11或当前版本的EDGE。



请勿在真实网站上使用,除非您有后备。 >



如果您正在寻找不依赖额外标记的解决方案,则可以将背景图像和过滤器应用到正文上的伪元素。 / p>

  body {
position:absolute;
top:0; bottom:0; left:0; right:0;
height:100%;
}
body:before {
content:;
position:absolute;
background:url(http://lorempixel.com/420/255);
background-size:cover;
z-index:-1; / *保持背景背后的内容* /
height:20%; width:20%; / *使用Glen Maddern的技巧/通过@mente * /

/ *不要忘记使用你需要的前缀* /
transform:scale(5);
transform-origin:top left;
filter:blur(2px);
}

Is it possible to use -webkit-filter: blur(); on background-image?

I have tried this code and it just blurs everything but the background-image:

body {
  background-image: url('http://www.publicdomainpictures.net/pictures/10000/velka/pebbles-and-sea-11284647414Rbeh.jpg');
  background-attachment: fixed;
  -webkit-filter: blur(5px);
}

I have been searching for a while but cannot find anyone resources describing how to do this.

解决方案

FUTURE USERS: This is not supported in IE7, IE8, IE9, IE10, IE11 or the current version of EDGE.

DO NOT USE on a real site, unless you have a fallback.

If you're looking for a solution that doesn't rely on extra markup, you could apply the background image and filter to a pseudo element on the body.

body {
    position: absolute;
    top: 0; bottom: 0; left: 0; right: 0;
    height: 100%;
}
body:before {
    content: "";
    position: absolute;
    background: url(http://lorempixel.com/420/255);
    background-size: cover;
    z-index: -1; /* Keep the background behind the content */
    height: 20%; width: 20%; /* Using Glen Maddern's trick /via @mente */

    /* don't forget to use the prefixes you need */
    transform: scale(5);
    transform-origin: top left;
    filter: blur(2px);
}
