The column-span CSS property makes it possible for an element to span across all columns when its value is set to all. An element that spans more than one column is called a spanning element.
Values

The element does not span multiple columns.
all
The element spans across all columns. Content in the normal flow that appears before the element is automatically balanced across all columns before the element appears. The element establishes a new block formatting context.

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. </div> </body> </html>
