Question

我正在尝试自定义我的rails应用程序导航栏并将css添加到application.css。我知道正在引用application.css，因为应用程序正在从中获取其他样式。但导航栏css试图覆盖bootstrap.css中已有的内容，并且应用程序无法识别它......

application.html.erb（layout）

<%= stylesheet_link_tag "application", :media => "all" %>
    <%= javascript_include_tag "application" %>
    <%= analytics_init if Rails.env.production? %>
    <link href="../assets/bootstrap-responsive.css" rel="stylesheet">

application.css

body {
  padding-top: 20px;
  padding-bottom: 60px;
}

/* Custom container */
.container {
  margin: 0 auto;
  max-width: 1000px;
}
.container > hr {
  margin: 0px 0;
}

/* Main marketing message and sign up button */
.jumbotron {
  margin: 20px 0;
  text-align: center;
}
.jumbotron h1 {
  font-size: 100px;
  line-height: 1;
}
.jumbotron .lead {
  font-size: 24px;
  line-height: 1.25;
}
.jumbotron .btn {
  font-size: 21px;
  padding: 14px 24px;
}

/* Supporting marketing content */
.marketing {
  margin: 60px 0;
}
.marketing p + h4 {
  margin-top: 28px;
}


/* Customize the navbar links to be fill the entire space of the .navbar */
.navbar .navbar-inner {
  padding: 0;
}
.navbar .nav {
  margin: 0;
  display: table;
  width: 100%;
}
.navbar .nav li {
  display: table-cell;
  width: 1%;
  float: none;
}
.navbar .nav li a {
  font-weight: bold;
  text-align: center;
  border-left: 1px solid rgba(255,255,255,.75);
  border-right: 1px solid rgba(0,0,0,.1);
}
.navbar .nav li:first-child a {
  border-left: 0;
  border-radius: 3px 0 0 3px;
}
.navbar .nav li:last-child a {
  border-right: 0;
  border-radius: 0 3px 3px 0;
}

我错过了什么吗？

Answer 1

尝试让您的application.css仅用于“需求”目的，它将为您跟踪错误以及利用Rails3资产管道堆栈铺平道路。

在你的app / assets / stylesheets / application.css中：

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 *= require_self
 *= require bootstrap
 *= require bootstrap_responsive
 *= require my_styles
 */

在你的app / assets / stylesheets / my_styles.css中，将你现在拥有的自定义css放在application.css中。

这样你的自定义样式将在所有引导程序之后加载，覆盖它。

说实话，我认为这就是你现在正在发生的事情：它不是bootstrap.css什么是覆盖你的风格，它是bootstrap_responsive，因为它是加载你的风格。< / p>

Answer 2

如果要使用自己的样式覆盖引导程序，则必须在引导程序定义后加载application.css。

Answer 3

您需要加载bootstrap.css和bootstrap-responsive.css，然后覆盖您的样式。一种方法是定义一个新的bootstrap_and_overrides.css.scss，如下所示：

@import "bootstrap";
@import "bootstrap-responsive";

.well {
  box-shadow: 0 0 4px #888888;
  border-radius: 0px 0px 0px 0px;
}
// more overrrides

然后在您的rails布局中包含application.css之前包含此文件。

获取application.css以覆盖引导程序
