我将如何去修改CSS来改变Twitter Bootstrap中导航栏的颜色?


tl;dr - TWBSColor - Generate your own Bootstrap navbar

Available navbars

You've got two basic navbars:

<!-- A light one -->
<nav class="navbar navbar-default" role="navigation"></nav>
<!-- A dark one -->
<nav class="navbar navbar-inverse" role="navigation"></nav>

Default color usage

Here are the main colors and their usage:

  • #F8F8F8 : navbar background
  • #E7E7E7 : navbar border
  • #777 : default color
  • #333 : hover color ( #5E5E5E for .nav-brand )
  • #555 : active color
  • #D5D5D5 : active background
  • Default style

    If you want to put some custom style, here's the CSS you need to change:

    /* navbar */
    .navbar-default {
        background-color: #F8F8F8;
        border-color: #E7E7E7;
    }
    /* Title */
    .navbar-default .navbar-brand {
        color: #777;
    }
    .navbar-default .navbar-brand:hover,
    .navbar-default .navbar-brand:focus {
        color: #5E5E5E;
    }
    /* Link */
    .navbar-default .navbar-nav > li > a {
        color: #777;
    }
    .navbar-default .navbar-nav > li > a:hover,
    .navbar-default .navbar-nav > li > a:focus {
        color: #333;
    }
    .navbar-default .navbar-nav > .active > a,
    .navbar-default .navbar-nav > .active > a:hover,
    .navbar-default .navbar-nav > .active > a:focus {
        color: #555;
        background-color: #E7E7E7;
    }
    .navbar-default .navbar-nav > .open > a,
    .navbar-default .navbar-nav > .open > a:hover,
    .navbar-default .navbar-nav > .open > a:focus {
        color: #555;
        background-color: #D5D5D5;
    }
    /* Caret */
    .navbar-default .navbar-nav > .dropdown > a .caret {
        border-top-color: #777;
        border-bottom-color: #777;
    }
    .navbar-default .navbar-nav > .dropdown > a:hover .caret,
    .navbar-default .navbar-nav > .dropdown > a:focus .caret {
        border-top-color: #333;
        border-bottom-color: #333;
    }
    .navbar-default .navbar-nav > .open > a .caret,
    .navbar-default .navbar-nav > .open > a:hover .caret,
    .navbar-default .navbar-nav > .open > a:focus .caret {
        border-top-color: #555;
        border-bottom-color: #555;
    }
    /* Mobile version */
    .navbar-default .navbar-toggle {
        border-color: #DDD;
    }
    .navbar-default .navbar-toggle:hover,
    .navbar-default .navbar-toggle:focus {
        background-color: #DDD;
    }
    .navbar-default .navbar-toggle .icon-bar {
        background-color: #CCC;
    }
    @media (max-width: 767px) {
        .navbar-default .navbar-nav .open .dropdown-menu > li > a {
            color: #777;
        }
        .navbar-default .navbar-nav .open .dropdown-menu > li > a:hover,
        .navbar-default .navbar-nav .open .dropdown-menu > li > a:focus {
              color: #333;
        }
    }

    $colHighlight: #ffbbbc;
    .navbar-default {
      background-color: $bgDefault;
      border-color: $bgHighlight;
      .navbar-brand {
        color: $colDefault;
        &:hover, &:focus {
          color: $colHighlight; }}
      .navbar-text {
        color: $colDefault; }
      .navbar-nav {
        > li {
          > a {
            color: $colDefault;
            &:hover,  &:focus {
              color: $colHighlight; }}}
        > .active {
          > a, > a:hover, > a:focus {
            color: $colHighlight;
            background-color: $bgHighlight; }}
        > .open {
          > a, > a:hover, > a:focus {
            color: $colHighlight;
            background-color: $bgHighlight; }}}
      .navbar-toggle {
        border-color: $bgHighlight;
        &:hover, &:focus {
          background-color: $bgHighlight; }
        .icon-bar {
          background-color: $colDefault; }}
      .navbar-collapse,
      .navbar-form {
        border-color: $colDefault; }
      .navbar-link {
        color: $colDefault;
        &:hover {
          color: $colHighlight; }}}
    @media (max-width: 767px) {
      .navbar-default .navbar-nav .open .dropdown-menu {
        > li > a {
          color: $colDefault;
          &:hover, &:focus {
            color: $colHighlight; }}
        > .active {
          > a, > a:hover, > a:focus, {
            color: $colHighlight;
            background-color: $bgHighlight; }}}
    }
    

    And finally, a little gift

    I've just made a script which will allow you to generate your theme: TWBSColor - Generate your own Bootstrap navbar

    [Update]: TWBSColor now generates SCSS/SASS/Less/CSS code.
    [Update]: From now, you can use Less as the default language provided by TWBSColor
    [Update]: TWBSColor now supports drop down menus colorization
    [Update]: TWBSColor now allows to choose your version (Bootstrap 4 support added)


    Updated 2018 for Bootstrap 4

    You can create a custom navbar class, and then reference it to change the navbar without impacting other Bootstrap navs..

    <nav class="navbar navbar-custom">...</nav>
    

    Bootstrap 4.0.0

    I know the original question was for 3.x, but I thought a new Bootstrap 4 example would be helpful too. The CSS required is much less in Bootstrap 4...

    .navbar-custom {
        background-color: #ff5500;
    }
    /* change the brand and text color */
    .navbar-custom .navbar-brand,
    .navbar-custom .navbar-text {
        color: rgba(255,255,255,.8);
    }
    /* change the link color */
    .navbar-custom .navbar-nav .nav-link {
        color: rgba(255,255,255,.5);
    }
    /* change the color of active or hovered links */
    .navbar-custom .nav-item.active .nav-link,
    .navbar-custom .nav-item:hover .nav-link {
        color: #ffffff;
    }
    

    Bootstrap 4 Custom Navbar Demo 在这里输入图像描述


    Bootstrap 3

    <nav class="navbar navbar-custom">
      <div class="navbar-header">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">...
        </button>
        <a class="navbar-brand" href="#">Title</a>
      </div>
       ...
    </nav>
    
    
    .navbar-custom {
        background-color:#229922;
        color:#ffffff;
        border-radius:0;
    }
    
    .navbar-custom .navbar-nav > li > a {
        color:#fff;
    }
    
    .navbar-custom .navbar-nav > .active > a {
        color: #ffffff;
        background-color:transparent;
    }
    
    .navbar-custom .navbar-nav > li > a:hover,
    .navbar-custom .navbar-nav > li > a:focus,
    .navbar-custom .navbar-nav > .active > a:hover,
    .navbar-custom .navbar-nav > .active > a:focus,
    .navbar-custom .navbar-nav > .open >a {
        text-decoration: none;
        background-color: #33aa33;
    }
    
    .navbar-custom .navbar-brand {
        color:#eeeeee;
    }
    .navbar-custom .navbar-toggle {
        background-color:#eeeeee;
    }
    .navbar-custom .icon-bar {
        background-color:#33aa33;
    }
    

    Custom Navbar Demo on Bootply


    If the Navbar has dropdowns, add the following to change dropdown color(s):

    /* for dropdowns only */
    .navbar-custom .navbar-nav .dropdown-menu  { 
      background-color: #33aa33;
    }
    .navbar-custom .navbar-nav .dropdown-menu>li>a  { 
      color: #fff;
    }
    .navbar-custom .navbar-nav .dropdown-menu>li>a:hover,.navbar-custom .navbar-nav .dropdown-menu>li>a:focus  { 
      color: #33aa33;
    }
    

    Demo with Dropdown


    Using Less

    You could also consider to compile your own version. Try http://getbootstrap.com/customize/ (which has a apart section for the Navbars settings (Default navbar and Inverted Navbar)) or download your own copy from https://github.com/twbs/bootstrap.

    You will find the navbar settings in variables.less . navbar.less is used to compile the navbar (depends on variables.less and mixins.less ).

    Copy the 'navbar-default section' and fill in your own color settings. Changing the variables in variables.less will be the easiest way (changing the default or inverse navbar won't be a problem because you have one navbar per page only).

    You won't change all settings in most cases:

    // Navbar
    // -------------------------
    
    // Basics of a navbar
    @navbar-height:                    50px;
    @navbar-margin-bottom:             @line-height-computed;
    @navbar-default-color:             #777;
    @navbar-default-bg:                #f8f8f8;
    @navbar-default-border:            darken(@navbar-default-bg, 6.5%);
    @navbar-border-radius:             @border-radius-base;
    @navbar-padding-horizontal:        floor(@grid-gutter-width / 2);
    @navbar-padding-vertical:          ((@navbar-height - @line-height-computed) / 2);
    
    // Navbar links
    @navbar-default-link-color:                #777;
    @navbar-default-link-hover-color:          #333;
    @navbar-default-link-hover-bg:             transparent;
    @navbar-default-link-active-color:         #555;
    @navbar-default-link-active-bg:            darken(@navbar-default-bg, 6.5%);
    @navbar-default-link-disabled-color:       #ccc;
    @navbar-default-link-disabled-bg:          transparent;
    
    // Navbar brand label
    @navbar-default-brand-color:               @navbar-default-link-color;
    @navbar-default-brand-hover-color:         darken(@navbar-default-link-color, 10%);
    @navbar-default-brand-hover-bg:            transparent;
    
    // Navbar toggle
    @navbar-default-toggle-hover-bg:           #ddd;
    @navbar-default-toggle-icon-bar-bg:        #ccc;
    @navbar-default-toggle-border-color:       #ddd;
    

    You could also try http://twitterbootstrap3navbars.w3masters.nl/. This tool generates CSS code for your custom navbar. Optionally, you could also add gradient colors and borders to the navbar.
