This text appears above a thick, unshaded, centered horizontal rule. This text appears below the horizontal rule. The COLS attribute is required. Netscape Navigator attempts to flow elements evenly across the columns to make each column be about the same height. If it is not specified, Netscape Navigator uses 10.
All columns are the same width.
Tags mark the start and the end of text. For example, you can use the H1 tag to mark text as a first-level heading. Even if all of your readers use Netscape Navigator, they all might not see your HTML page in the same way because they can configure Netscape Navigator to use different fonts and to override your color settings. The file multicol.htm shows this example in action in a separate window. The NOBR tag ensures that a line of text does not wrap to the next line.
