我有一个网站,其中对于移动视图我想要不同的图像和桌面视图,我想要另一个。
对于桌面视图,以下HTML / CSS代码工作正常:
HTML:
<div class="et_pb_section et_pb_section_0 demo-request-backgroundimage et_pb_with_background et_section_regular">
</div>
的 CSS:
div.et_pb_section.et_pb_section_0 {
background-image: url(/wp-content/uploads/2018/05/contactusheader-2-min.jpg)!important;
}
我现在想要为移动视图实现的目标,我希望调用以下CSS,但我不确定为什么在移动视图中未调用以下背景图像。
@media only screen and (max-width: 767px)
{
.demo-request-backgroundimage
{
background-image: url(/wp-content/uploads/2018/05/mobilecontactusheader.jpg) !important;
background-size: cover;
background-repeat: no-repeat;
}
}

您要更改.et_pb_section.et_pb_section_0
img,以便media-query
使用:
请参阅jsFiddle:https: https://jsfiddle.net/smuf3c3t/
.et_pb_section.et_pb_section_0 {
background-image: url(https://material.angular.io/assets/img/examples/shiba1.jpg)!important;
width:500px;
height:500px;
}
@media only screen and (max-width: 767px)
{
.et_pb_section.et_pb_section_0
{
background-image: url(https://material.angular.io/assets/img/examples/shiba2.jpg) !important;
background-size: cover;
background-repeat: no-repeat;
}
}

<div class="et_pb_section et_pb_section_0 demo-request-backgroundimage et_pb_with_background et_section_regular">
</div>

这是因为您在媒体查询之外使用更多特异性。尝试:
@media only screen and (max-width: 767px) {
div.et_pb_section.et_pb_section_0 {
background-image: url(/wp-content/uploads/2018/05/mobilecontactusheader.jpg) !important;
}
}

尝试使用多个classname
普通Css的一类 和 其他媒体查询
