Setting the Header Page Occurrence

Specify the pages on which a header appears using the occurrence attribute of <ctheader>. For example, if you want a header to only appear on even-numbered pages, you can use the following tag:
<!--<ctheader occurrence="even"><p>This is an even page.</p></ctheader>-->
Acceptable values for the occurrence attribute include: all, allbutfirst, odd, oddbutfirst, and even.
Highwire supports multiple headers, each with different occurrence settings. For example, you can define one header that occurs on odd pages and another header that occurs on even pages.
Setting Header Margins

Because the header is placed in the top margin of the page, that margin must be big enough to contain the header. If the margin isn't big enough and the header is cut off, you can change the page's top margin. For more information, see Document Margins.
Header margins control the position of the header within the page's top margin. Header margins do not affect the page margins. To change header margins, use the style attribute of <ctheader>, which supports the following styles: margin, margin-left, margin-right, and margin-top. For example, the following code defines a header with a margin of 2 inches on the sides:
<ctheader style="margin-left:2in;margin-right:2in">My Header</ctheader>
Change the margin size by replacing 2in with another size definition (such as 72pt). Size definitions require a number followed by a unit of measurement. Valid units of measurement include: in, cm, mm, px, pc, pt, em, and ex. The default header margin is .25 in.
