How to prevent fixed header from overlapping content when browser resized?

Hello Gurus!

This page works just like I want, except for one thing: when the browser window is resized so that the header buttons take up two rows, the now height-expanded header encroaches upon the beginning of the content. What I wish would happen is that the entire content block would adjust down to make room for the height-expanded header. (Can you tell I'm new at this?) Any help greatly appreciated!

Don't used fixed or absolute positioning because it removes the element from the normal flow.

Hi Chris,

Thank you for your reply. When I remove "position: fixed;" from header_container, undesireable effects are produced: the header doubles in height (?!), and the header scrolls up with the rest of the page. What I'm trying for is to only have the header's height expand when the buttons will no longer fit in one row across the browser window, and have the header stay always at the top of the page, so that the content scrolls up underneath it. There must be a way! I humbly submit for your kind attention.
 
In that case give the fixed positioning on #header and set #header_container to relative, that way it will constrain #header during resizing but allow it to break out when scrolled.

as demonstrated here

Chris.
