The 'display' property controls what area an element generates.
Your options are: inline | block | list-item | run-in | compact | marker | table | inline-table | table-row-group | table-header-group | table-footer-group | table-row | table-column-group | table-column | table-cell | table-caption | none
Every element is inline by default.
If you want vertical layouts, use 'block'.
