html - 中心导航栏链接没有品牌在 Bootstrap 4 中将其推到右侧？

Question

我试图将我的导航栏链接居中，但是当我这样做时，我的品牌标志将它推到右边，所以它没有居中。这是我的 html ...

<nav class="navbar navbar-toggleable-md navbar-light main-nav">
  <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <a class="navbar-brand" href="index.html">Brand Name</a>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mx-auto clearfix">
      <li class="nav-item active">
        <a class="nav-link" href="index.html">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" href="#">Link</a>
      </li>
    </ul>

  </div>
</nav> 

如何阻止品牌 Logo 影响我的导航栏链接的位置。

Answer 1

发生这种情况是因为相邻的 flexbox 项目相对于彼此的位置。

一个选择是使用 flexbox utils 和右侧的全宽占位符元素。 navbar-brand 也使用 w-100 util 类设置为全角。

<nav class="navbar navbar-toggleable navbar-inverse bg-primary justify-content-center">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarCenter">
        <span class="navbar-toggler-icon"></span>
    </button>
    <a href class="navbar-brand d-flex w-100 mr-0">Brand is Wider Name</a>
    <div class="navbar-collapse collapse" id="navbarCenter">
        <ul class="navbar-nav mx-auto text-center">
            <li class="nav-item">
                <a class="nav-link" href="#">Link</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Center</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Link</a>
            </li>
        </ul>
    </div>
    <div class="d-flex w-100"> </div>
</nav>

另一种选择是绝对定位 .navbar-nav..

@media (min-width: 567px) {
    .abs-center-x {
        position: absolute;
        top: 5px;
        left: 50%;
        transform: translateX(-50%);
    }
}
