我的媒体查询不会覆盖常规CSS,除非我一直使用!important
。错误是什么?在这里,您可以看到带有!important
s的CSS。如果我删除它们,样式会回到常规CSS,即使屏幕小于850px。能否请你帮忙?

浏览器如何在没有!important
的情况下查看您的CSS:
for screen 200px < x < 800px do this {
bla bla bla
}
but... wait a second.. forget about it, do this for all screens {
bla bla bla
}
当您添加!important
时,浏览器将采用以下方式:
for screen 200px < x < 800px do this {
bla bla bla
!do not listen to me if I will ever give you any other instructions
}
but... hey dude, want any instructions? Can you do this for all screens? {
bla bla bla
}
如果您将@media
块放在文件的末尾并删除所有!important
,则它将如下所示:
for all screens do this {
bla bla bla
}
but for screens 200px < x < 800px do this {
bla bla bla
}
以完整页面模式打开此代码段并尝试更改浏览器的窗口大小
@media (max-width: 800px) {
.bad {
background-color: green;
}
}
.bad, .good {
width: 100px;
height: 100px;
background-color: firebrick;
}
@media (max-width: 800px) {
.good {
background-color: green;
}
}
&#13;
<div class="good"></div>
<div class="bad"></div>
&#13;

翻转订单以稍后放置媒体查询。它似乎没有添加任何选择器权重,因此后者优先。
所以你会(剪掉):
/usr/hdp/2.2.6.3-1/hadoop/mapreduce.tar.gz
例如,请参阅CSS specificity on MDN,不列出hdfs://<fqdn for the namenode>:8020/hdp/apps/2.2.6.3-1/mapreduce/
- 查询增加权重。
答案 2 :(得分:0)
css样式优先顺序
优先级最明确定义规则。 例如: 1) .class1 { .class2 { .class3 {color:green} } }
2) .class1 { .class3 {color:red} }
答案 3 :(得分:0)
您必须检查<head>
标签。首先,包含主要样式的css文件,然后包含响应式css文件。
类似这样的东西:
<link rel="stylesheet" type="text/css" href="mainstyle.css">
<link rel="stylesheet" type="text/css" href="reponsive.css">

放置响应css 。问题会解决。
答案 5 :(得分:0)
我有同样的问题。我通过将媒体查询样式放在其他样式的末尾来解决它。
