Epub is basically a zipped directory with html, css and media files. The html easyly flows according to differrent page sizes, but some elements, as <pre> or <code>, need non-standard styling, else they break out of right border of page. That overflow isn't visible. Images also need some attention, to make them fit on the visible page, i use as '.css' something like:
img { max-width: 100%; height: auto; } Files of other types, like .txt or office suites, need to be converted, to bee visible. Greetings , Karl-Heinz
