Block Level Elements

Each block level element possesses peripheral characteristics called margins, padding, and border. Together, these elements control how elements appear relative to text and graphical content contained within them, and when positioned next to or within each other:

Element Description
Text Area All runs of text describe a rectangle defined by the most extreme points at the top, right, bottom and left of the text. The text rectangle includes the leading between lines of text. In Microsoft Reader, italic fonts may produce a degree of horizontal overhang that may cause runs of text to extend slightly outside of the official text rectangle on the right side of the block.

Border Box The border box allows content authors to create a border around block elements that can be any supported color or width.
