How to blur only background and not content in Ionic/CSS
提问by JohnAndrews
I am trying to have a blurred background for my content.
我正在尝试为我的内容设置模糊的背景。
So far I tried this:
到目前为止,我试过这个:
.background-image {
background-image: url('../img/background/image.jpg');
width: 100vw;
height: 100vh;
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
-o-filter: blur(10px);
-ms-filter: blur(10px);
filter: blur(10px);
}
and then
接着
<ion-view class="background-image">
// header, content, footer etc
<ion-view>
But then I get the problem that the whole screen is blurred and not only the background as follows:
但是后来我得到了整个屏幕模糊而不仅仅是背景的问题,如下所示:

put content out side the blurred div.
将内容放在模糊的 div 之外。
.background-image {
background-image: url('../img/background/image.jpg');
width: 100vw;
height: 100vh;
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
-o-filter: blur(10px);
-ms-filter: blur(10px);
filter: blur(10px);
}
<div class="background-image"></div>
<div>Content</div>

there is an other way come to my head which is add second background-image
,
which in css3 you can have multi background
for one element, and the second one can be a blur image, even with low quality , like this
我想到了另一种方式,即添加第二个background-image
,在 css3 中,您可以background
为一个元素设置多个,而第二个可以是模糊图像,即使质量很低,就像这样
in sass
在 sass
#element
background:
image: url(/*first url*/), url(/*second url*/)
size: auto auto /*first one*/, 100% 100% /* second one*/
i guess second will cover first or revers , you can try it out
我想第二个将覆盖第一个或反向,您可以尝试一下

Put the image outside the other div... Like this:
将图像放在另一个 div 之外......像这样:
<div class="background-image"></div>
<div class="content">
<p>Here goes your content</p>
</div>
