I'm currently using the default Wordpress theme Twenty Twelve for my website located at: .
My goal is to have the navigation menu always stay at the top of the page while scrolling, similar to a site called wpsites (I can't provide the link due to stackoverflow's restrictions).
If you'd like to check out the CSS for the theme, you can find it here: http://pastebin.com/muXyT6AY
I'm unsure how to achieve this myself. Currently, I've managed to create clickable links in the navigation bar that scroll to specific sections on the page, but the menu doesn't stick to the top as desired. Any help or guidance would be greatly appreciated!
