我在居中li时遇到问题，因为它们都在导航栏的正确位置，并且垂直居中。我希望它们在调整大小时也不会从导航栏中剪切出来。

margin: 0;

.nav-list {

.nav-items {

right: auto;
display: inline-block;
font-size: 20px;
padding: 0 1vw;
}<div class="main-site">
<nav>
<ul class="nav-list">
<li class="nav-items"><a href=""> Item 1</a></li>
<li class="nav-items"><a href=""> Item 2</a></li>
<li class="nav-items"><a href=""> Item 3</a></li>
<li class="nav-items"><a href=""> Item 4</a></li>
</ul>
</nav>
</div>您只需要删除导航的视图高度并停止绝对定位。使用flexbox，下面的导航css将在调整大小时做出响应。

</body>在导航元素上使用display flex，而不是暴力绝对定位：(
