Which html tags can I use in the header and footer

The header and footer paramaters should contain valid HTML markup with the following classes used to inject printing values into them:

• date: formatted print date
• title: document title
• url: document location
• pageNumber: current page number
• totalPages: total pages in the document

For example, the following markup will generate Page N of NN page numbering:

<span style='font-size:10px'>Page <span class='pageNumber'></span> of <span class='totalPages'></span>.</span>

Please note that the top and bottom page margins are important because the page content may overlap the footer or header.
