I'm trying to put some html elements (images) in columns and, depending on the resolution, it would be 1, 2, 3 or 4 columns. For example, if I had 11 images, I would like to put them in this way (3 columns in this case):
1    2    3
4    5    6
7    8    9
10   11
I've got a code that creates the columns depending on the resolution of the screen, but it puts the columns like this:
1    5    9   
2    6    10
3    7    11
4    8
Could you help me?

  column-count:         4;
  column-gap:           10px;
}
#pics img {

  -webkit-column-count: 3;
  column-count:         3;
  }
}
@media (max-width: 500px) {
  #pics {
  -moz-column-count:    2;
  -webkit-column-count: 2;
  column-count:         2;
  }
}
