CSS

Question

我正在尝试均匀分布导航栏，使其分布在整个页面上，而不是像目前那样在右侧留出空隙。

我如何使用 CSS 实现此目的？

HTML

    <nav class="navbar navbar-default" role="navigation">
        <!--– Brand and toggle get grouped for better mobile display –-->
        <div class="container">
        <div class="navbar-header">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        </button>

        <!--– Collect the nav links, forms, and other content for toggling –-->
        <div class="collapse navbar-collapse in navbar-ex1-collapse">
        <ul id="menu-main-menu" class="nav navbar-nav divider"><li id="menu-item-20" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-8 current_page_item menu-item-20 active"><a title="Find Your Home" href="http://localhost/radleigh/find-your-home/">Find Your Home</a></li>
<li id="menu-item-21" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-21"><a title="About Us" href="http://localhost/radleigh/about-us/">About Us</a></li>
<li id="menu-item-22" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-22"><a title="Helping You Move" href="http://localhost/radleigh/helping-you-move/">Helping You Move</a></li>
<li id="menu-item-23" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-23"><a title="News" href="http://localhost/radleigh/news/">News</a></li>
<li id="menu-item-24" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-24"><a title="Get in Touch" href="http://localhost/radleigh/get-in-touch/">Get in Touch</a></li>
</ul>        </div><!--– /.navbar-collapse –-->
        </div><!--– /.container –-->
        </div>
    </nav>

Answer 1

要均匀分布您的 link，您可以将 display:table 用于 navbar，将 display:table-cell 用于 li，我将在媒体中使用查询 768px 以上以避免改变移动视口上的导航。

还添加了一些媒体查询以补偿 font-size 和 link 标题的长度。

*您的 HTML 也有一些不一致之处。您的结束 navbar-header div 应该在 .navbar-collapse 之前而不是之后。

查看整页示例代码段。

.navbar.navbar-default {
  background-color: #002e5d;
  border-radius: 0;
  font-size: 18px;
}
.navbar.navbar-default .navbar-nav > li > a {
  color: #fff;
}
.navbar.navbar-default .navbar-nav > li > a:hover,
.navbar.navbar-default .navbar-nav > li > a:focus {
  color: #e8e8e8;
}
.navbar.navbar-default .navbar-nav > .active > a,
.navbar.navbar-default .navbar-nav > .active > a:focus,
.navbar.navbar-default .navbar-nav > .active > a:hover {
  background-color: #1b66b2;
  color: #FFF;
}
.navbar.navbar-default .current_page_item {
  background: #1b66b2;
  font-weight: 700;
}
.navbar.navbar-default .navbar-toggle .icon-bar,
.navbar.navbar-default .navbar-toggle .icon-bar:hover {
  background-color: #fff;
}
.navbar.navbar-default .navbar-toggle {
  border-color: #fff;
}
.navbar.navbar-default .navbar-toggle:focus,
.navbar.navbar-default .navbar-toggle:hover {
  background-color: #1b66b2;
}
@media (max-width: 991px) and (min-width: 768px) {
  .navbar.navbar-default .navbar-nav > li > a {
    padding-left: 5px;
    padding-right: 5px;
    white-space: nowrap;
  }
}
@media (min-width: 768px) {
  .navbar.navbar-default .navbar-nav {
    margin: 0;
    display: table;
    width: 100%;
  }
  .navbar.navbar-default .navbar-nav > li {
    display: table-cell;
    float: none;
    padding-top: 10px;
    padding-bottom: 10px;
  }
  .navbar.navbar-default .navbar-nav > li > a {
    text-align: center;
  }
  .navbar-default .navbar-nav li:not(:last-child) {
    border-right: solid 1px #FFF;
  }
  .navbar.navbar-default .navbar-header .navbar-brand {

}
@media (max-width: 767px) {
  .navbar.navbar-default {

    padding-bottom: 10px;
  }
  .navbar.navbar-default .navbar-collapse {
    border: none;
    box-shadow: none;
  }
  .navbar.navbar-default .navbar-header .navbar-brand {
    color: #fff;
    font-size: 28px;
    font-weight: bold;
  }
}
@media (max-width: 360px) {
  .navbar.navbar-default .navbar-header .navbar-brand {
    font-size: 24px;
  }
}

Answer 2

默认的 Bootstrap 样式不支持您想要的行为，因此您需要覆盖其中的几个。为了方便并防止这些新样式（可能）影响其他元素，我在您的导航栏中添加了一个 id 字段：

<div id="myNavbar" class="navbar-header">

然后我用自己的样式覆盖不需要的样式：

#myNavbar {
    float: none;
}
#myNavbar > .navbar-collapse {
    float: none;
}
#menu-main-menu {
    float: none;
    text-align: center;
}
#menu-main-menu > li {
    float: none;
    display: inline-block;
}

如您在此 jsfiddle update 中所见，导航选项卡现在位于页面中央。
