#gallery margin and padding

I was watching the lecture 6 first video, when nick write this in his main.css file:

#gallery {
  margin: 0;
  padding: 0;
  list-style: none;
}

I do not quite understand why do we need to set margin and padding to zero. I did comment those and see the differents, the ul tag is gone, but i want to know the purpose of doing this thanks.

If you check out this section in the developer tools, you'll notice that some margin and padding have been defined in the normalize.css By setting margin and padding to zero in main.css you'll overwrite them so they fit your layout.
