Question

我使用引导程序具有以下导航栏

我已使用以下代码段<body> <nav class="navbar navbar-default"> <div class="container-fluid"> <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="http://www.someone.com/">Home</a> </div> <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> <ul class="nav navbar-nav"> <li><a href="#" data-toggle="modal" data-target="#myModal">About</a></li> </ul> </div> </div> </nav> </body>

创建了它

css

但是我想将此导航栏居中到页面中心，如下所示

我需要知道如何使用其他{{1}}样式。

Answer 1

您可以尝试这样：

在这里，我在第二行添加了一类navbar-content。

<nav class="navbar navbar-default">
  <div class="container-fluid navbar-content">
    <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="http://www.someone.com/">Home</a>
    </div>

    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li><a href="#" data-toggle="modal" data-target="#myModal">About</a></li>
      </ul>
    </div>
  </div>
</nav>

在您的css文件中放置波纹管样式。

.navbar-content {
  display: flex;
  justify-content: center;
}

Answer 2

将margin: 0 auto;应用于导航栏类以居中。

.navbar {
width: 500px;
margin: 0 auto;
}

<nav class="navbar navbar-default">
        <div class="container-fluid">
            <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="http://epidemicdash.epizy.com/">Home</a>
                    <a class="navbar-brand" href="http://epidemicdash.epizy.com/">User</a>
                    <a class="navbar-brand" href="http://epidemicdash.epizy.com/">About</a>
            </div>    
            
            <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
                <ul class="nav navbar-nav">
                    <li><a href="#" data-toggle="modal" data-target="#myModal">About</a></li>
                </ul>
            </div>
        </div> 
    </nav>
