How to centre div contents?

Question

I know this might seem like a very simple question but how can i get the contents/images of the div (#thumbs_vases) to sit central within the div whatever the screen size but at the same time, when the screen size gets small enough the images stack beneath each other still remaining in the center of the div? Currently they do stack beneath each other when screen reduces in size but they sit to the left.

1. Add text-align: center; to the container (in your case #thumbs_vases.)
2. Remove float from the elements inside and add display: inline-block; to them (in your case #thumbs_vases p.)
