Question about html

Question

how can I set a background image in html?
I found how to put an image in the body but I didn't find how to put an image only in one part(in a table, in <div>... ) and not in the whole page
I need to put a background image in the <header> section. Please help me

Answer 1

Many options but i recommend using css:
header{
background-image: url('path/to/image');
}
