I have been playing with adding information about authors into the comments section of the metadata of my books, including their pictures. To make the authors' pictures viewable in Calibre-Web, instead of adding the pictures as links to files on my computer, I'm embedding the images as html (basically converted jpg files into Base64) and it looks very nice.
But I am looking to do some more styling. More specifically, adding a table with just one row, so that I could put the author's image next to the text describing the author, instead of above or below. The outcome looks ok in Calibre, but on any other platform the result is distorted. For example the image becomes tiny.
So, I've done some investigating and realized I could accomplish what I'm looking for with CSS and I've tried some WYSIWYG html editors, but they all seem to create a full html page and from what I understand, the comments section in Calibre only takes very basic div elements, so the styling is gone.
So, this is the question: is there any way to do some rich styling in the comments section or this is it?
