我正在使用以下home.html文件和一个名为＆＃34; navbar.css＆＃34;的外部css文件。我在＆＃34; bootstrap.min.css＆＃34;之后加载。我试图通过分配一个名为＆＃34; custom-menu-item＆＃34;的类来完成工作。到适当的元素并更改＆＃34; navbar.css＆＃34;中的填充（但是没有对填充进行更改）
.custom-menu-item{
padding:10px 13px;
} <!DOCTYPE html>

在boostrap css文件后添加自己的样式：
.nav > li > a {
padding: 40px;
}
<!DOCTYPE html>
<html >
<head>
<title>Home</title>
<meta charset="utf-8">
