Page breaks and file splitting
Hello.
I was wondering wether there is a way to split an epub into more html files (so it's not too heavy to handle) without having page breaks between one file and the next one, so you don't notice anything while reading it, i.e. so it flows seamlessly from beginning to end. Hope I made myself clear Thanks. |

Ah, I think I know the answer to this one...
No. I don't know if it is actually a part of the EPUB specification, and I'm too lazy to look it up, but all the readers I've come across have an implicit page break on new files. There's no way to work around it, I'm afraid, apart from writing your own custom reader... |

Ha. Thanks.
So, you know how much an html file can weigh before the reader starts having problems processing it? |

Hang on, I know that one too...
300kB And that's according to the EPUB spec. Some readers are forgiving, and permit larger files, others (e.g. my old PRS-505) don't. |

Actually, I do not think that the 300kB is in the actual specs. It is really depending on the reader. A lot of older readers have limited memory and processors and those really limit the size.
Also, it is actually closer around 286kB |

Even if a large file doesn't break it, it can slow it down.

260K (calibe's default) is a safer number if Images, fonts are aso to be used.
And yes it BREAKS (as in crash) the reading ap on many MRSDK based devices. Smaller is even better as you point out: Big (of under 260K) files do sloooow things down a whole lot. |

( weren't scrolls read side to side anyway?) With dead tree books you read a real page(tm) and then either have to look to the right or Flip with a massive delay before your eyes track and lock on to the new starting point to continue reading. The Horrors of printed books! |

Flowing seamlessly into eyestrain and headache I think. They could publish books (and they did) on scrolls if seamlessly was so desirable. This sounds like a programmer's idea, not a reader's.

Code:
page-break-before: avoid; Where did that go, exactly? It was created for exactly this usage situation, and I can't imagine any reader would refuse to respect that. Put that in the top element of each new page (or alternatively, use page-break-after: avoid; at the END of each page). In fact, calibre will automatically split all files above a certain size (configurable) during every ePub conversion, for EXACTLY this reason, and takes care of adding the page-break-(whichever):avoid. Although this shouldn't be a problem in any book that splits on each chapter... |

No reader I know will honor this... It should avoid a pagebreak before an element within the same HTML file, not between HTML files.
