What did you have in mind? I've recently looked at quite a few PG ePubs and the formatting seemed fairly reasonable to me. The only slightly unusual feature I noticed is the way they add the labels for physical page numbers with, for example:
Code:
<span class="pagenum pncolor"><a id="page_10"></a>10</span>
using a media query:
Code:
@media screen {
hr.ppg-pb {
margin: 30px 0;
width: 100%;
border: none;
border-top: thin dashed silver
}
.pagenum {
display: inline;
font-size: x-small;
text-align: right;
position: absolute;
right: 2%;
padding: 1px 3px;
font-style: normal;
font-variant: normal;
font-weight: normal;
text-decoration: none;
background-color: inherit;
border: 1px solid #eee
}
.pncolor {
color: silver
}
}
I quite like the appearance of this, though: an inconspicuous boxed page number in light grey ("silver") in the right margin.
