导航栏和下拉栏之间的空间

Question

我对html很新，当我尝试创建网页时遇到了问题。我设法在“游戏”部分下方直接创建一个带有下拉菜单的导航栏，但是如果我向下滚动并打开下拉菜单，它就不再直接在导航栏下打开。这是我的HTML代码。

<div class="wrapper">
    <div id="main-title">
        <header>
            <h1>Max Reviews</h1>
        </header>
    </div>                                                                              <!-- Title box-->
        <div id="nav">                                                                  <!-- Navigation Bar -->
            <nav>                                                                   
                <ul>
                    <li><a class="active" href="#">Home</a></li>
                    <li><a href="about.html">About Me</a></li>                          <!-- Link to about page -->
                    <li class="drop">
                        <a href="games.html" class="dropbtn"><p>Games</p></a>
                        <div class="drop-content">
                            <a href="rfg.html"><p>Red Faction: Guerrilla</p></a>                    <!-- Contains links to the respective pages -->

                    <li><a href="reviews.html">Reviews</a></li>
                    <li><a href="external.html">External Store</a></li>                 <!-- Link to external site -->
                    <li><a href="video.html">Videos</a></li>                            <!-- Contains links to Youtube -->
                </ul>
            </nav>
        </div>
  <div class="image">                                                               <!-- Banner-->

请帮助我，因为我一直试图解决这个问题2天。另外，这是我第一次在这里发布一个问题，所以请原谅我，如果我错误地缩进了我的代码，或者我无意中违反了Stack Overflow的一些规则。

Answer 1

此行为的原因是您的弃用内容在悬停时有position:fixed。

来自MDN：

  

......一个绝对定位的元素被从流中取出;因此，其他元素的位置就好像它不存在一样。绝对定位的元素相对于其最近定位的祖先定位...固定定位类似于绝对定位，除了元素的包含块是视口。

Working example on JSFiddle这就是我改变了：

#nav ul {
  /*overflow: hidden;*/
}

.drop:hover .drop-content {
  /*position: fixed;
  top: 155px;*/
  position: absolute;
}

将CSS更新为

   border: 0;
   padding: 0;
   margin: 0;
}

完成了2次更改。

1. 已移除overflow:hidden
中的#nav ul
2. Keot display:block仅限于.drop:hover .drop-content
