What are the different parts of the profile called in html?

ok so ive gotten a way for my pictures (thanks) but now im a bit confused about what parts of the profile are called what

i got it to look like how it currently is by just typing div where p is here:

<style>
p {
  background-image: url('img_girl.jpg');
}
</style>

but it doesnt look quite right

thanks in advanceee
