Custom CSS Styles during export document to epub format

Hi Team,

I want to add few custom css styles to exported epub document. I am using aspose.words.net for export word document to epub format.

I try with this code :

builder.InsertHtml("<h1>Heading1</h1><style type=\"text/css\">.MyCustomStyle {margin-top: 3em;}</style>");

H1 tag is working, but style element is not rendered in the out put epub file.

Goal: I want margin should be on “em” in epub file.

Any comments are highly appreciated

Thanks,
Arun Chandran C
