Why doesn't margin-top work?

Question

css

I'm trying to indent
photos from all sides in 5px but for some reason margin-top is ignored. How to decide?

Answer 1

Because img is an inline element. And grids, yes. cool.....

Answer 2

Maybe padding? As I understand it, you want to indent the picture, not the block?
#grid div { padding: 5px }

Answer 3

I margin-topdon't see it in the code at all..
