推荐答案

您只能使用CSS来做到这一点，使用与所选菜单项的ID相关的单词来设置房屋的ID，例如此处.

You can do that with CSS only, setting the id of the home with a word related to the id of the selected menu item, like described here.

或使用Javascript，将当前页面的URL与菜单项的URL(如果它们为href)进行匹配，如

Or with Javascript, matching the URL of the current page with the URL of the menu items (if they're href), like described here (approach #2)

或者使用JSP标记等...

Or do it with JSP tags, etc...
