Here are a couple of styling examples.

This is a two-column using only inline styles.

[column style="background:#00f;color:#fff;float:left;margin-right:2%;padding:1%;width:46%;"]

This column has a very lovely blue background.

[/column]

[column style="background:#f00;color:#fff;float:left;margin-left:2%;padding:1%;width:46%;"]

This column is quite red. Quite.

[/column][endrow]

Three-column layout that uses the H5BP clearfix on the row div, and achieves equal height across the columns using the One True Layout Method as discussed on CSS-Tricks.

.diy-row {
  margin-bottom: 20px;

  *zoom: 1;

.diy-row:before, .diy-row:after {
  content: "";
  display: table;
