我为我的wordpress主题启用了自定义背景,如下所示:
add_theme_support('custom-background', array(
'default-color' => 'FFF',
'default-image' => get_template_directory_uri() . '/img/bg.jpg'
));
比我抓住身体的“.custom-background”类,因为我想改变背景大小:
body.custom-background {
background-attachment: fixed!important;
background-position: center center!important;
background-repeat: no-repeat!important;
background-size: cover!important;
top: 0;
right: 0;
bottom: 0;
left: 0;
position: absolute;
}
我将它定位为绝对的唯一原因是,因为我想添加具有相同背景属性但宽度为1000px且居中边距(0自动)的其他背景,以使用css-filters模糊此部分:< / p>
body.custom-background:before {
content: "";
background-image: url(""); //here he should takes the custom background-image (of body.custom-background)
background-attachment: fixed!important;
background-position: center center!important;
background-repeat: no-repeat!important;
background-size: cover!important;
height: 100%;
right: 0;
left: 0;
margin: 0 auto;
width: 1000px;
position: fixed;
z-index: -1;
filter: blur(10px);
}
但是当然wp不知道哪个是背景图像...那么,我怎样才能解决这个问题 - 他将自定义背景图像再次放到:选择器之前?
希望你理解我的意思。

您可以在header.php中编写以下代码
<?php $background = set_url_scheme( get_background_image() ); ?>
<style>
body.custom-background:before {
content: "";
background-image: url("<?php print $background; ?>");
background-attachment: fixed!important;
background-position: center center!important;
background-repeat: no-repeat!important;
background-size: cover!important;
height: 100%;
right: 0;
left: 0;
margin: 0 auto;
width: 1000px;
position: fixed;
z-index: -1;
filter: blur(10px);
}
</style>
这会有用......
