Question

我使用绝对定位在容器底部定位了bootstrap nav-tabs，并且它在一个问题上工作得非常好：一旦我定位绝对，它就不再是容器的全宽度了。这是一张图片：

HTML：

<div class="container-fluid">
  <ul class="nav nav-tabs profile-nav">
    <li class="nav-item">
      <a class="nav-link active" href="#">Active</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">Link</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">Link</a>
    </li>
    <li class="nav-item">
      <a class="nav-link disabled" href="#">Disabled</a>
    </li>
  </ul>
</div>

CSS：

.profile-nav{
  position: absolute;
  bottom: 0;
  transform: translateY(50%);
  background-color: #fff;
  box-shadow: 0px 0px 8px rgba(0, 0, 0, 0.15);
}

.profile-nav .nav-item{
  padding-top: 15px;
  padding-bottom: 15px;
}

图像容器具有位置：relative，以便像那样定位导航。所以，正如我所说，问题是，我无法使其成为容器流体的全宽。

Answer 1

添加irb(main):001:0> s = "A123" # Create string to split. => "A123" irb(main):002:0> a, b = s.split(/\d/) # Extracts letter only. => ["A"] irb(main):003:0> puts a # a got assigned 'A' as expected. A => nil irb(main):004:0> puts b # b did not get assigned the split remainder, '123'. => nil irb(main):005:0> b = s.split(/\D/) # Extracts number only. => ["", "123"] irb(main):006:0> puts b # Now b has the value I want it to have. 123 => nil＆amp; left: 0;至width: 100%;

.profile-nav

.profile-nav {
  position: absolute;
  bottom: 0;
  transform: translateY(50%);
  background-color: #fff;
  box-shadow: 0px 0px 8px rgba(0, 0, 0, 0.15);
  /* add these */
  width: 100%;
  left: 0;
}

.profile-nav .nav-item {
  padding-top: 15px;
  padding-bottom: 15px;
}

要修复导航标签的底部，您需要使用引导程序类navbar-fixed-bottom

将项目包装到导航栏中

<nav class="navbar navbar-default navbar-fixed-bottom profile-nav">

我认为nav-tabs不是最适合底层菜单的形式。请尝试使用nav-pills。

看一下片段

.profile-nav {
  background-color: #fff;
  box-shadow: 0px 0px 8px rgba(0, 0, 0, 0.15);
  border: none;
}

.profile-nav .nav-item {
  padding-top: 15px;
  padding-bottom: 15px;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<nav class="navbar navbar-default navbar-fixed-bottom profile-nav">
 <div class="container-fluid">
   <ul class="nav nav-pills">
    <li class="nav-item">
      <a class="nav-link active" href="#">Active</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">Link</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">Link</a>
    </li>
    <li class="nav-item">
      <a class="nav-link disabled" href="#">Disabled</a>
    </li>
  </ul>
 </div>
</nav>
