column-fill

The column-fill CSS property controls how contents are partitioned into columns. Contents are either balanced, which means that contents in all columns will have the same height or, when using auto, just take up the room the content needs.
 

Values

auto
Is a keyword indicating that columns are filled sequentially.
balance
Is a keyword indicating that content is equally divided between columns.

On the Insert tab, the galleries include items that are designed 
to coordinate with the overall look of your document. You can use 
these galleries to insert tables, headers, footers, lists, cover 
pages, and other document building blocks.
 
When you create pictures, charts, or diagrams, they also coordinate
with your current document look.You can easily change the formatting
of selected text in the document text by choosing a look for the 
selected text from the Quick Styles gallery on the Home tab. You can 
also format text directly by using the other controls on the Home tab. 
Most controls offer a choice of using the look from the current 
theme or using a format that you specify directly.
 
To change the overall look of your document, choose new Theme elements 
on the Page Layout tab. To change the looks available in the Quick 
Style gallery, use the Change Current Quick Style Set command. Both 
the Themes gallery and the Quick Styles gallery provide reset 
commands so that you can always restore the look of your document 
to the original contained in your current template.
