To use borders in Microsoft Word 2007, you begin by clicking on the Page Layout tab. Next, click on Page Borders. This will open a window. Page borders will border the entire page. You are able to custom choose the width of the lines, the style of the border, or the color of the border. The color drop down menu will allow you to choose automatic colors or custom colors. You can also choose to remove one or more of the sides. You can decide which pages to add borders to, as well. There are also options under the border tab, which will allow you to set up borders within the page.
