Freezing the top header of a webpage in GoDaddy's Website Builder
I would like to know how to "freeze" the top section of our website so that as one scrolls down the page, top stays fixed. I would also like to "freeze" the menu on the left. Here is the website:
I built this site several years ago using at that time GoDaddy's Website Tonight. GoDaddy has since "upgraded" to Website Builder. I would like to improve our website and this is one of the things I would like to start with. I talked to GoDaddy's Tech Support and they said I would have to add "code" to do this and that they can not help me. I am not a Web Designer and I have tried researching this and have been given examples using CSS or HTML but I can not figure out how to get this to work.
Thanks in advance,
