How do you center horizontally and vertically?

This way:

To center text horizontally:

1. Right-click on it and select Paragraph.

2. In the Alignment list box, select Centered.

3. Click OK.

To center text vertically:

1. Click on the page.

2. In the Page Layout tab on the Ribbon, click on the arrow in the lower right corner of the Page Setup group.

3. Click the Layout tab.

4. In the Page section, in the Vertical Alignment list box, select Center.

5. Click OK.

That should do it.
