Question

我已经创建了一个带有下拉菜单的简单顶部导航栏，我试图使所有链接（包括下拉菜单）居中。

我一直在寻找并尝试了各种方法来使所有内容居中，以便在分辨率较低的移动设备，平板电脑或屏幕上使用时可以自动调整，但是我仅设法使下拉菜单或其他链接居中...我该怎么办？

这是我正在使用的代码




body 
.navbar {
  overflow: hidden;
  background-color: #221a57;
}

.navbar a {
  float: left;
  font-size: 16px;
  color: white;
  text-align: center;
  min-width: 160px;
  padding: 14px 16px;
  text-decoration: none;
}

.dropdown {
  float: left;
  overflow: hidden;
}

.dropdown .dropbtn {
  font-size: 16px;  
  border: none;
  outline: none;
  color: white;
  min-width: 192px;
  padding: 14px 16px;
  background-color: inherit;
  font-family: inherit;
  margin: 0;
}

.navbar a:hover, .dropdown:hover .dropbtn {
  background-color: #F73D4B;
}

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #DDDDDD;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
  z-index: 1;
}

.dropdown-content a {
  float: none;
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

.dropdown-content a:hover {
  background-color: #ddd;
}

.dropdown:hover .dropdown-content {
  display: block;
}

您可以使用display：flex;证明内容：中心；然后您可以根据需要固定宽度，而无需溢出

<!DOCTYPE html>
    <html>
    <head>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
    <style>
     
    .navbar {
     
      background-color: #221a57;
      display:flex;
      justify-content:center;
    }
     
    .navbar a {
      font-size: 16px;
      color: white;
      text-align: center;
      
      padding: 14px 16px;
      text-decoration: none;
    }


    .dropdown .dropbtn {
      font-size: 16px;  
      border: none;
      outline: none;
      color: white;

      padding: 14px 16px;
      background-color: inherit;
      font-family: inherit;
      margin: 0;
    }

    .navbar a:hover, .dropdown:hover .dropbtn {
      background-color: #F73D4B;
    }

    .dropdown-content {
      display: none;
      position: absolute;
      background-color: #DDDDDD;
     
      box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
      z-index: 1;
    }

    .dropdown-content a {

      color: black;
      padding: 12px 16px;
      text-decoration: none;
      display: block;
      text-align: left;
    }

    .dropdown-content a:hover {
      background-color: #ddd;
    }

    .dropdown:hover .dropdown-content {
      display: block;
    }
    </style>

    <div class="navbar">

      <div class="dropdown">
        <button class="dropbtn">Freebies 
          <i class="fa fa-caret-down"></i>
