在OSX上使用Bootstrap 4将Navbar UL(无序列表)居中

嗯,我似乎无法自己解决这个问题。我正在使用主Navbar,并且似乎无法将特定内容集中在页面上。我已经应用了#con; .container'到导航.navbar'并设置' max-width'控制"品牌"排队。但是,我遇到了居中问题" Home |链接|禁用|下拉"在页面的中心。

我试过了:

<option selected >Tamil</option>

但是,它都不起作用。这是Nav标记和CSS文件: HTML:

‘.text-center’ on the li tags, inline
and:
li {
  text-align: center;
}

‘justify-content-center’ on ul tag, inline
and
.ul {
      justify-content: center;
    }

Put the ul inside:
<div class="row">
  <div class="col text-center”>

  </div>
</div>

萨斯/ CSS

<nav class="navbar navbar-expand-md navbar-light bg-light fixed-top">
    <div class="container">
    <a class="navbar-brand" href="#">Brand Here</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>

    <div class="collapse navbar-collapse" id="navbarsExampleDefault">
      <!-- ul starts here -->

      <ul class="navbar-nav mr-auto">
        <li class="nav-item active">
          <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></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>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="http://example.com" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a>
          <div class="dropdown-menu" aria-labelledby="dropdown01">
            <a class="dropdown-item" href="#">Action</a>
            <a class="dropdown-item" href="#">Another action</a>
            <a class="dropdown-item" href="#">Something else here</a>
          </div>
        </li>
      </ul>

      <!-- ul ends here -->
      </div>
    </div><!-- container placed within <nav> tag -->
  </nav>

任何帮助将不胜感激。 TIA

要将导航栏内容集中在Bootstrap V4中,请使用flex-grow: 1;它允许元素展开100%,使用justify-content: center;属性将项目对齐到中心。

@media (min-width: 992px){
.navbar-expand-lg .navbar-nav {
      flex-grow: 1;
      justify-content: center;
     }
  }

谢谢Satheesh,你让我走上了正确的道路。我在我的Sass文件中逐字尝试了你的解决方案,但由于某种原因,它没有工作。然后我刚补充说:

body {
  padding-top: 56px;

  nav .container {
    max-width: 1374px;

    .navbar-brand {
      color: $blue-text !important;
    }
    /* added from your solution */
    .navbar-nav {
      flex-grow: 1;
      justify-content: center;
    }
  }
}
