.logo {
background-image: url(https://ofbuckleyandbeatles.files.wordpress.com/2011/01/testpattern.gif);
background-size: 100%;
}
@media(max-width:767px) {
.logo {
background-image: url(https://ofbuckleyandbeatles.files.wordpress.com/2011/01/testpattern.gif);
background-size: 50%;
background-repeat: no-repeat;
}
}
<div class="logo"> </div>
我无法弄清楚为什么这不起作用 - 为什么图像无法呈现的任何想法?
HTML:
<div class="logo"> </div>
CSS:
.logo {
background-image: url(../img/logo_white.png);
background-size: 100%;}
@media(max-width:767px) {
.logo {
background-image: url(../img/logo_white.png);
background-size: 50%;
background-repeat: no-repeat;}
}
任何帮助非常感谢

首先,你的语法错了。其次,至少在你提供的代码中,你的div是零大小。看看它是如何工作的:
.logo {
display: block;
width: 99%;
height: 400px;
border: solid 1px red;
background-image: url('http://phandroid.s3.amazonaws.com/wp-content/uploads/2014/10/mountains.jpg');
background-size: 100%;
}
@media only screen and (max-width: 767px) {
.logo {
background-size: 50%;
background-repeat: no-repeat;
}
}
&#13;
<div class="logo"></div>
&#13;
但是你想要响应式设计吗?你可能误解了background-size: 50%;
属性的含义?

Uhm mate,这是一个简单的问题:给你的包装器一些高度。
.logo {
background-image: url(https://ofbuckleyandbeatles.files.wordpress.com/2011/01/testpattern.gif);
background-size: 100%;
width: 100%;
height: 100px;
}
@media(max-width:767px) {
.logo {
background-image: url(https://ofbuckleyandbeatles.files.wordpress.com/2011/01/testpattern.gif);
background-size: 50%;
background-repeat: no-repeat;
}
}
&#13;
<div class="logo"> </div>
