Borders are lines that can be drawn around any or all of the four sides of a page. In terms of the CSS box model, increasing the padding for a page style increases the space between the content within the page and the border of the page.

Not all browsers display border styles the same way. For example, some browsers may not differentiate dotted lines from solid lines. The size and spacing of the dots in a dotted line may also be different between various browsers and operating systems. Some browsers may not display page borders at all. If you want a page border, view the generated output in multiple browsers to verify that your settings create the appearance you want.
