Header that remains static

[Guest]

I want my header to remain visible whilst scrolling down a page

You can do it with frames-- just put in in the top frame--works well but
web designers avoid frames nowdays.

Or CSS positioning--it is tricky and you need to tweek to acount for
various broswers mis-behaviors.

See an explanation of positioning

Then google for examples of what you want.
