Vertically align horizontal inline-block elements

You can take a look here, I've made it from scratch...

So what I did here is, I've used display: table; for the container element and am using display: table-cell; for the child div and as the child div are now table cells, I used vertical-align: top; so that the elements align to the top in those cells

section {
  display: table;
  width: 100%;
}

section > div {
  vertical-align: top;
  display: table-cell;
  width: 33%;
  text-align: center;
}
