HTML Support for PDF Landing Pages

Page Size

To define the page size for the document, supply a size page rule.

You can specify either a length (not a percentage) for width and height.

@page {
	size: 8.5in 9in;
}

Or one of the standard sizes A3, A4, A5, B3, B4, Letter, Legal, Ledger.

@page {
	size: A4;
}

Where the standard sizes can optionally be followed by portrait or landscape.

@page {
	size: A4 landscape;
}

While it is theoretically possible to apply different sizes to different pages, Open HTML To PDF does not cope well with this, so it is strongly recommended to stick to a single size for the whole document that is specified in a general @page rule, as shown above.
