That doesn't change the margins in Sigil's Book View? Or are you talking about when viewing it on the Nook? Because I don't think the @page rule really affects Sigil's Book View. But you should see the effect on your Nook or in ADE.
I'm assuming the stylesheet you're adding the @page to is linked to all the xhtml files in you're trying to affect?
I have no idea why I've adopted the method I have; but I tend to assign left and right margin directly to the <body> element:
Code:
body {
margin-left: 3px;
margin-right: 3px;
}
and then use @page for some top and bottom margin:
Code:
@page {
margin-top: 5pt;
margin-bottom: 5pt;
}
It probably had something to with wanting to SEE (in Sigil) that I had the left/right margins the way I wanted them.
