试图显示此下拉菜单，但我不确定出什么问题。

<body>
          <div class="container">
              <!-- will add in later -->
            <div class="header" <img>
            </div>
            <div class="menu">
              <nav>
                <ul>
                  <li><a style="text-decoration:none" href="Home">Home</a></li>
                  <li><a style="text-decoration:none" href="Home">About</a></li>
                  <li><a style="text-decoration:none" href="works.html">Works</a>
                    <ul class="sub-menu">
                      <li> Digital </li>
                      <li> Physical </li>
                      <li> Animation </li>
                    </ul>
                  <li><a style="text-decoration:none" href="Home">Contact</a></li>
                </ul>
              </nav>
            </div>

Answer 1

首先，子菜单的文本显示为黑色（这是默认颜色），这就是为什么您在黑色背景上看不到它的原因。将color: #fff添加到ul.sub-menu li以使其可见。然后，您可以修复其余部分。

替换此CSS
