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.
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);
}
