html - html css nav list hover problems

Question

I have all li with a hover background, but is there away instead of not:lastchild like not: id1 id4 ? Cause i want some li without that hover effect.

nav ul li.selected, nav ul li:hover, nav ul li:focus{
    background-color: #0047B2;
}

Answer 1

只需将 ID 写为特定情况即可。

nav ul li#id4 {
    background-color: none;
}

Answer 2

您必须为所有想要具有悬停效果的元素提供一个类，并且只需在 css 文件中指定该类。
