This is a bunch of text split into three columns using the CSS column-count property with a value of 3. It also includes a column-height value of 95vh. The column-wrap value is set to its initial value, auto; when a column-height value is included, column-wrap: auto resolves to wrap, which allows the columns to wrap onto multiple rows. The text is equally distributed over the columns, and placed into multiple rows.

The column-height and column-wrap properties were introduced in CSS Multi-column Layout Module Level 2.
