Navigation menu with highlight in Asp.NET MVC?

Question

It\'s a simple question. How did stackoverflow do their menu in Asp.net MVC, with highlight on what page we are on.

Answer 1

If you look at the page source, they've added a css class to the <li> element to change the background color. I'm guessing the code looks at what controller the user is accessing (questions, users, etc) and adds the class to that section's <li> tag.
