Fixed Header vs. Anchors - workaround?

I’ve found to my annoyance that if I place a fixed header on a page anchor tags put the starting text under it. Any workarounds outside of js?

Michael, can you please clarify what you mean? I do not understand what is “fixed” within the header (position, width, height, etc) nor where the anchor tags lie… around certain text in the header or around other text?
A snippit of code might help, too.
