Question

我已经通过CSS文件向我的页面添加了一些CSS。但是，当我加载页面时，CSS没有被应用。

当我查看firebug时，CSS样式显示为空，即

.logomain img {
}
.logocorn {
}

然而，当我点击源编辑时，他们会显示？即

.logomain img {
    width: 40% !important;
    padding-left: 40px !important;
}

.logocorn {
    float: right !important;
}

任何想法发生了什么？

Answer 1

CSS文件似乎格式正确，请参阅此jsFiddle。

其他CSS样式是否会应用于您的网页，例如

body {
    color: #7E7171;
    font-family: 'Open Sans',sans-serif;
    font-weight: 300;
}

？如果没有，似乎整个CSS文件没有被正确加载 - 并且该解决方案需要更多关于您的环境的信息=）

控制台中的任何错误消息？

Answer 2

@media (min-width:1200px)的结束括号未正确关闭。

    @media (min-width: 1200px) {

    #add_this {
        margin: 0 auto;
        width: 242px;
    }
    .col-md-9 img:nth-of-type(1) {
        width: 0;
    }
    .logomain img {
        padding-left: 40px !important;
        width: 40% !important;
    }
    .logocorn {
        float: right !important;
    }

}

您在任何样式之前关闭了@media。在您的帖子中，您有@media (min-width:1200px) { }

Answer 3

首先，如果您将css称为外部css，
然后检查......确实关闭了css的所有括号？和/或分号也适用于每种风格，
然后还检查媒体查询括号是否正确关闭？，
最后在浏览器中运行并按Ctrl + F5进行刷新...它将删除旧stlyes中的缓存..

Answer 4

我想知道你的课程设置在哪里，是<div>会扩大屏幕或容器的宽度，还是像<span>或<a>那样。如果没有，请在<div>上试用。

另外，如果你使用bootstrap，你可以尝试使用 .pull-left 和 .pull-right 这两个类，因为它们已经有了很好的相关规则。

CSS未应用，样式显示为空白？
