我在网上搜索教程，他们都说要使用 float: right;但这似乎不起作用

body {
  margin: 0;
  padding: 0;
  margin-top: 130px;
  overflow-x: hidden;
}

.nav-menu a img {
  float: left;
  margin-left: 10px;
}

.nav-menu ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: rgba(0, 0, 0, 0.9);
  margin-top: -130px;
}

.nav-menu li {
  float: left;
}

.nav-menu li a,
.dropbtn {
  display: inline-block;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}

.nav-menu li a:hover,
.dropdown:hover .dropbtn {
  border-top: 2px solid #ff0000;
}

.nav-menu li.dropdown {
  display: inline-block;
}

.nav-menu .dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.nav-menu .dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

.nav-menu .dropdown-content a:hover {
  background-color: #ff0000;
  color: #fff;
}

.nav-menu .dropdown:hover .dropdown-content {
  display: block;
}

.nav-menu li.social {
  float: right;
}

<div class="nav-menu">
  <ul>
    <a href="#"><img src="img/logo.jpg" style="width:50px"></a>
    <li class="dropdown">
      <a href="javascript:void(0)" class="dropbtn">Games</a>
      <div class="dropdown-content">
        <a href="#">Link 1</a>

    <li><a href="#">News</a></li>
    <li class="social">
      <a href="#">Sign In</a>
      <a href="#" style="color:#ff0000">Sign Up</a>
      <li><a href="#"><i class="fas fa-search"></i></li></a>
  </ul>

问题是你的<li>包装搜索图标。这是无效代码。 <li>不能是 <li> 的 child .将其更改为 <a>元素

body {
  margin: 0;
  padding: 0;
  margin-top: 130px;
  overflow-x: hidden;
}

.nav-menu a img {
  float: left;
  margin-left: 10px;
}

.nav-menu ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: rgba(0, 0, 0, 0.9);
  margin-top: -130px;
}

.nav-menu li {
  float: left;
}

.nav-menu li a,
.dropbtn {
  display: inline-block;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}

.nav-menu li a:hover,
.dropdown:hover .dropbtn {
  border-top: 2px solid #ff0000;
}

.nav-menu li.dropdown {
  display: inline-block;
}

.nav-menu .dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.nav-menu .dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

.nav-menu .dropdown-content a:hover {
  background-color: #ff0000;
  color: #fff;
}

.nav-menu .dropdown:hover .dropdown-content {
  display: block;
}

.nav-menu li.social {
  float: right;
}
