CSS resposive divs inside container

I have a div that acts as a container.
.cont {
I have 10 boxes that will be inside of that container.  so each box has a width of 20% so I can have two rows of 5.
.container-box {
what do I add to the css to keep each of those boxes proportionate in height so they remain square? And so the text remains centered both vertically and horizontally?
