I had tested the export to HTML5 only briefly yet. When I use the default export settings (and some tweaks), the export looks good in my browser and on my smartphone.
One thing does not work. When there are several paragraphs in a table title, all paragraphs are concatenated and do not have any font information. Which means Times or something like this.
With a single paragraph everything is fine.
Is there anything which I can do about this? What can I do that the export maintains the separate paragraphs?
Possibly I will have more questions in the next days.
