Question

我正在尝试在网站的导航栏中实现输入/搜索字段。我非常希望它可以像YouTube导航栏一样工作，其中输入字段位于左侧徽标和右侧链接之间。而且还可以使输入字段的宽度动态变化，并在浏览器页面宽度减小时压缩。

我对CSS不熟练，我甚至可以将搜索字段放置在导航栏中的唯一方法是将位置设置为绝对（在输入字段类中）。我知道您可以使用CSS以多种不同方式完成相同的结果，而且我知道，如果要保持动态，那么摆弄职位当然是错误的方法。

请在下面找到一个JSFiddle以及html / CSS代码。我正在使用MaterializeCSS创建网站，并且当浏览器窗口低于特定阈值时，将使用“ brand-logo”类将徽标居中。然后，我在ul上使用“隐藏并隐藏”类，以使徽标居中时链接消失。但是，我在下面的JSFiddle中删除了“隐藏在下面并隐藏”类，以使搜索输入当前的工作方式更加明显。

  <nav>
    <div class="nav-wrapper">
      <a href="#" class="brand-logo">
        <div class="logo-text" href="#"><object href="#" class="logo-svg"></object>LOGO</div>
      </a>
      <ul class="right hide-on-med-and-down">
        <li><a href="#">Link 1</a></li>
        <li><a href="#">Link 2</a></li>
        <li><a href="#">Link 3</a></li>
        <li><a href="#">Link 4</a></li>
      </ul>
    </div>
    <div class="input-field hide-on-med-and-down">
      <input type="text" class="autocomplete z-depth-0" id="autocomplete-input" placeholder="Search.." />
    </div>
  </nav>

CSS代码：

  body,
  html {
    height: 100%;
    width: 100%;
    margin: 0;
    font-size: 16px;
    background-color: var(--main-bg-color);
  }

  /* Navigation bar */

  nav {
    position: fixed;
    background: rgba(0, 0, 0, 0.4);
    z-index: 20;
    height: 80px;
    line-height: 80px;
  }

  nav .nav-wrapper {
    padding: 0px 50px;
  }

  nav .logo-text {

    display: block;
  }

  nav ul a:focus {
    text-decoration: underline;

请尝试以下代码，我已尝试编写尽可能简单的代码，以便您可以轻松地根据需要更改CSS参数。（看一下HTML，您会发现我已经将输入块代码的位置移到了ul列表上方。）
