这是我的代码
#menu-navigation li:first-child{

应用于此 HTML 时:
<ul class="nav" id="menu-navigation">
<li>Home</li>
<li>About Us
<ul>
<li>Our Team</li>
</ul>
</li>
</ul>?
...both "Home" and "Our Team" turn red.
...“家”和“我们的团队”都变红了。

use the child selector:
使用子选择器:
#menu-navigation>li:first-child{
color:red;
}?

回答by Mike
Wouldn't it be easier to just use an id/class?
仅使用 id/class 不是更容易吗?
<li class="red"> Our Team </li>
.red
{
color: red;
}
Alternatively you could use an ID...
<li id="red"> Our Team </li>
#red
{
color: red;
}
