I've built a header bar for my page. It consists of the element and inside are some elements, , . I can lay everything out nicely but when I resize the browser window everything starts to move and overlap in the header. Giving the header, or even the body a fixed with like "width: 1000px" solves this, but that is screen-size dependent.
How can I have my page such that any resizing of the browser window causes scroll bars to appear to view the hidden content, and where this would NOT be dependent on a hard-wired resolution in pixels.
