I have an .indd document that I need to export to HTML.
The intent was to export the document and upload to a server so anyone with the link to the document can read it on a desktop, smartphone etc.
the exported file looks good as I have the image headers flow with the text but the font that was in the original document does not convert over in the html.
How can I get the font to display as I clearly need to upload the font folder and need to know how I attache.
You're not going to be able to use your desktop fonts on a web site. You'll need to use actual web fonts (available from TypeKit as well as many other vendors). You could add the proper code to the header of the HTML document to utilize those web fonts when the user views the page. See the instructions for each web font vendor for instructions.
That is not the purpose of InDesign HTML export.
It is to get the content only.
For design, either use Publish Online or buy in5 from ajarproductions.com
Why not export PDF?
