Internal pattern table

When a single document requires a special pattern, an external pattern table should be used. You can use tags to define internal pattern tables in the head of the document, like what:

Hr {color: sienna;} p {margin-left: 20px;} body {background-image: url ("images/back40.gif");} inline style
