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;
