Instead of colour how would you put a background image in?

Question

background image with text over the top of it?

Answer 1

you should use CSS background's properties :

background: url('image_file_name_path');

... with generic 'background' instead of 'background-image' ( 'background-color' in case of color reference ).
Look at the other background's properties relative to image ( like placement, repetition or sizing ) for fine tuning ^^
