Question

我正在尝试使用Bootstrap 4创建一个固定的导航栏，但是我很难按照自己的喜好对齐LOGO和MENU项。

我知道这里有ml-auto，mr-auto，我是否可以向其中添加像素，以便按照自己的意愿精确地移动它？

这是我的导航栏的样子：

我希望将LOGO和MENU项目移到屏幕中间。可能从左右两边的100px开始，因此LOGO和MENU靠得很近。这是我的代码：

<nav class="navbar navbar-expand-lg navbar-dark sticky-dark bg-dark">
        <a class="navbar-brand" href="#">LOGO</a>
        <button class="navbar-toggler " type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div id="navbarNavDropdown" class="navbar-collapse collapse">

            <ul class="navbar-nav ml-auto"> 
                <li class="nav-item">
                    <a class="nav-link" href="#">HOME</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">ABOUT</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">SERVICES</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">CONTACT</a>
                </li>
            </ul>
        </div>
    </nav>

您可以将填充添加到主要.navbar元素中。然后使用媒体查询控制间距。

.navbar {
  padding: 0.5em 100px !important;
}

@media only screen and (max-width: 768px) {
  .navbar {
    padding: 0.5em 1em !important;
  }
}

    <ul class="navbar-nav ml-auto">
      <li class="nav-item">
