Sigil v. 0.9.16.
I use the plugin EpubCheck_v0.4.1.4, whereas a friend uses the standalone version.
I created a book with some errors, due to unattentiousnes, such as
Code:
<h1><div>...</div></h1>
As far as I know, divs should not be embedded in h1 elements. And the other:
Code:
<span class="center">...</span>
What I learned is that spans should only be used embedded in block elements, what has been missing here.
Now the strange is that epubcheck didn't put out an error message in the Sigil plugin version (for neither of the errors), but it did in the standalone version. Is there something one should know about that?
