Css覆盖nodejs express bootstrap

Question

我已经使用 Java+Spring 开发了一个用于移动设备的 Web 应用程序，由于响应缓慢，我现在正尝试在 node.js 上实现相同的东西，表达。

我将 bootstrap.css 和 styles.css 用于我的站点特定样式和一些 bootstrap 覆盖。在我的旧实现中，一切都正常工作，但现在在 nodejs 上，引导程序中的所有样式都被正确应用到我的标记中，而来自 styles.css 的所有覆盖都被 chrome 忽略。知道我错过了什么。

这是我的问题的示例演示

来自 html 的一些标记

<div class="row">
        <ul id="tabs-menu" class="nav nav-tabs">
          <li class="active"><a href="#bollywood" rel="1">Bollywood</a></li>
          <li><a href="#western" rel="3">Western</a></li>
          <li><a href="#pakistani" rel="2">Pakistani</a></li>
          <li><a href="#islamic" rel="4">Islamic</a></li>
        </ul>
</div>

由 chrome 检查的 css 属性

    //from bootstrap
    .nav-tabs > li > a:hover {
        border-color: #eeeeee #eeeeee #dddddd;
    }

    //from bootstrap
    .nav > li > a:hover, .nav > li > a:focus {
        text-decoration: none;
        background-color: #eeeeee;
    }

    //from bootstrap
    .nav-tabs > li > a {
        margin-right: 2px;
        line-height: 1.428571429;
        border: 1px solid transparent;
        border-radius: 4px 4px 0 0;
    }

    //from bootstrap
    .nav > li > a {
        position: relative;
        display: block;
        padding: 10px 15px;
    }

    //from style.css
    .nav>li>a {
        color: #000;
        background: #ddd;
    }
    //from style.css
    .nav>li>a {
        padding: 3px 1px 3px 1px; //ignored
        margin-bottom: 1px;
        margin-right: 1px; //ignored
        border-radius: 0px; //ignored
        font-size: 13px;
    }

问题是 style.css 中最后带有 //ignored 注释的样式被 chrom 忽略，而在我之前的实现中，完全相同的代码可以完美运行。

这是我的 style.css

另外还有 layout.jade，如果它有助于理解我的问题

doctype html
html
  head
    title= title
    meta(http-equiv='X-UA-Compatible', content='IE=edge')
    meta(name='viewport', content='width=device-width', initial-scale='1.0')
    meta(name='author', content='Khushal Khan')
    meta(name='description', content='Mobilink Streaming Web App')
    link(rel='stylesheet', href='/stylesheets/style.css')
    link(rel='stylesheet', href='/stylesheets/bootstrap.css')
    link(rel='shortcut icon', href="/images/favicon.ico")

    //
      script(src='/javascripts/less-1.3.3.min.js')

    //if lt IE 9
      script(src='/javascripts/html5shiv.js')

    script(type='text/javascript', src='/javascripts/jquery.min.js')
    script(type='text/javascript', src='/javascripts/bootstrap.min.js')
    script(type='text/javascript', src='/javascripts/scripts.js')
  body
    block content

Answer 1

好的，我认出了几件事：

• 首先：您给出的第一个示例不起作用可能是因为您的// comments。 CSS 中的// 不是标准的，所以一些浏览器会误解。
• 第二：对我来说，除了这些// 问题之外，您的示例代码运行良好。
• 第三：我相信你的问题来自于首先调用你个人的 style.css 并且被给定的 bootstrap.css 部分覆盖。

请尝试下面的代码，我在其中更改了链接的 css 文件的位置：

doctype html
html
  head
    title= title
    meta(http-equiv='X-UA-Compatible', content='IE=edge')
    meta(name='viewport', content='width=device-width', initial-scale='1.0')
    meta(name='author', content='Khushal Khan')
    meta(name='description', content='Mobilink Streaming Web App')
    link(rel='stylesheet', href='/stylesheets/bootstrap.css')
    link(rel='stylesheet', href='/stylesheets/style.css')
    link(rel='shortcut icon', href="/images/favicon.ico")

    //
      script(src='/javascripts/less-1.3.3.min.js')

    //if lt IE 9
      script(src='/javascripts/html5shiv.js')

    script(type='text/javascript', src='/javascripts/jquery.min.js')
    script(type='text/javascript', src='/javascripts/bootstrap.min.js')
    script(type='text/javascript', src='/javascripts/scripts.js')
  body
    block content
