无边框下拉菜单

Question

下拉菜单有问题，没有边框

我曾尝试自己更改单词，但没有成功，有人想帮助我解决这个问题。这可能是一件小事，但我刚刚开始编写一个网站，所以我对此还不太了解。没有这个，我就无法继续我的网站，所以如果有人这么好帮助我，那就太好了！

Answer 1

下面的答案将与您的下拉菜单相邻

注意：您的 CSS 代码一团糟:)。它使我的代码崩溃。要使用我的代码，您需要保存一份 css 文件的副本以备备份。然后删除css文件中的所有内容。然后将下面的 css 代码粘贴到空的 css 文件中。对 html 文件执行相同操作。

ul {
    list-style: none;
}
  
li {
    box-shadow: 2px #cccccc;
    border: 1px ridge black;
    /*width: 300px;*/
}

#ul-outer li{
    width: 300px;
}

#ul-inner li{
    width: 259px;
}

然后用下面的代码替换你的 HTML 代码

<div class="wrapper">
    <nav role="navigation">
      <input type="checkbox" id="show-search">
      <input type="checkbox" id="show-menu">
      <label for="show-menu" class="menu-icon"><i class="fas fa-bars"></i></label>
      <div class="content">
      <div class="logo"><a href="Home.html">GameRelease</a></div>
        <ul class="links" id="ul-outer">
          <li><a href="Home.html">Home</a></li>
          <li><a href="latest games.html">Latest games</a></li>
            <li><a href="#"></a> </li>
          <li>
            <a href="#" class="desktop-link">The recommended games</a>
            <input type="checkbox" id="show-features">
            <label for="show-features">Features</label>
            <ul id="ul-inner">
              <li><a href="Metal Gear V.Html">Metal Gear V</a></li>
              <li><a href="WRC9.html">WRC9</a></li>
              <li><a href="forzamotorsport7.html">Forza Motorsport 7</a></li>
              <li><a href="#">Drop Menu 4</a></li>
            </ul>
          </li>
      </form>
    </nav>  
    </div>
