4.8 - [back] Built-In
Mnemonic aid: back for BACKground color
This is a component of HTML 4.01s style-based color support. Refer to [color] for example of its use.
[back] Sets the background attribute of the HTML style applied with the [color] built-in. This only applies when [mode 4.01s] ; in [mode 3.2] , <font> is used to set the font foreground color, but background color is under the various control of the page and block elements such as tables and table cells.
