Hello,
I am looking for the CSS code to change the background color of the menu bar in specific pages. Someone can help me?
Thanks in advance.

You can target an item on a particular page by using .page-id-## (where ## is the id of the page) at the start of the selector of the item you want to change. The issue with a menu is you have menu items, sub-menu items, hover items etc. so this can get rather involved.

No problem with sub menus : they won't be any luckily!
I tried (between other things) :

.page-id-86 #menu1{
background-color: #EB7F00 !important;
}

but it doesn't work. I'm not really in coding just pretending as you can read ;-)
Could you help me please.

There are the separate menu tabs etc you have to think about. Maybe something like the following.

.page-id-86 #menu1, .page-id-86 #rmenu2 li {
    background: #EB7F00 !important;
}

It works perfectly. Many thanks.
