Make the header and menu bar stay on top

Hello Sakin, Using Catch Everest Pro Our site is : www.lacostafilmfestival.com I have see some other websites that have the top part (header and menu bar) stay fixed at the top even when you scroll down to the bottom. An example is http://sdfilmfest.com/. Can this also be done without too much effort on Catch Everest Pro? If so - is it possible for you to share the instructions to do so? Thanks!
