How do I add an ID or CLSS attribute to elements in Div Hunt

I tried to give my navbar an ID and a Class, where it says advanced settings, add attribute and it did save. however on the front end of the site, the ID or Class will not show up on the element. Is there another spot I should be doing this?

Hi,

From settings tab you can add ID or Class. But most common place for adding classes is Design tab.
