Question

我正在使用引导程序导航栏，我在导航栏中有我的链接。链接默认为左侧。我能够将链接移动到页面中心的唯一方法是使css为第一个列表项提供20em的边距。我想让它适应不同尺寸的显示器，但是如果显示器更大，它仍然会居中。以下是我的链接及其下方的CSS的bootstrap导航代码的一部分：

<nav class="navbar navbar-default">
    <!--<div class="container">-->
      <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand" href="#">Chompsta</a>
      </div>
      <!-- Collect the nav links, forms, and other content for toggling -->
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav">
          <li class="margin-left"><a href="#">Chat anonymously</a></li>
          <li><a href="#">Register for fame</a></li>
          <li><a href="#">Search for topics</a></li>
        </ul>
        <ul class="nav navbar-nav navbar-right">
          <li><div id="points">172</div></li>
        </ul>
      </div><!-- /.navbar-collapse -->
    <!--</div>&lt;!&ndash; /.container-fluid &ndash;&gt;-->
  </nav>

css

.margin-left { margin-left: 20em; }

这可能会解决您的问题或让您朝着正确的方向前进。这将使您的主navbar-right个链接居中，并使您的@media (min-width: 768px) { .navbar .navbar-nav { display: inline-block; float: none; vertical-align: top; } .navbar .navbar-collapse { text-align: center; } }保持在其中。

function getPixel(x, y, pixels) {

    var pointer = pixels.offset + (pixels.stride[0] * x) + (pixels.stride[1] * y);

    for(var i=0; i<4; i++) {
        out.push(pixels.data[pointer + (pixels.stride[2] * i)]);
    }

    return out;
}

使用bootstrap导航栏，并希望使用CSS中心链接
