最初のメニューが強調表示されない、または最後の 2 つのメニューが強調表示されるのはなぜですか。画像に何か関係があると確信していますが、もしそうなら、それを修正する方法がわかりません。
私のHTML：
<link type="text/css" rel="stylesheet" href="Practise.css"/>
<title>Practise</title>
</head>
<img src="404SQN logo.png" width="1250" class="logo"/>
<nav>
<ul>
<li><a href="#">Home</a></li>
<li class="drop">
<a href="#">About Us</a>
<div class="dropdownContain">
<div class="dropOut">
<div class="triangle"></div>
<ul>
<li>About 404SQN</li>
<li>About AAFC</li>
<li>What to Expect</li>
<li>Discipline</li>
</ul>
</div>
</div>
</li>
<li><a href="#">News</a></li>
