Placing text or other items in the middle of a page gives the page a visually appealing, well-organized appearance. To place text in the horizontal middle of the page -- centered between the left and right margins -- simply use the "Center" button on the "Ribbon." Place text in the vertical middle of the page -- centered between the top and bottom margins -- by using the advanced Page Setup options; although more difficult than simply centering text, this option offers an easier and more accurate method than pressing "Enter" until reaching the middle of the page.
