page-break-after: always not working

[franc]

Hallo

I made some experiments in an ebook's css-file (an epub) with the css property "page-break-after" and "page-break-before" like this:

...
.endofsite { 
	page-break-after: always;
	}
.beginofsite { 
	page-break-before: always;
	}

where I gave that class to a tag at the end (.endofsite) or the begin (.beginofsite) but never that makes any pagebreak in my ebook-Reader.
Tried it with calibre reader and MoonReader, neither are doing pagebreak.

Is there a way beside of creating a new html-file that my readers are doing a page break?

Thanks for hints.

Sorry, page-break-before/after are not supported consistently. The only way I am aware of forcing it is by having a new html page.

It does work in the calibre reader if coded correctly. I suspect that there is a problem with either the linking of the style sheet or calling out the class from the HTML.

@ franc --- this may or may not be of help -----
If you are working with epub2, you might take a look at this old thread:
https://www.mobileread.com/forums/sh...d.php?t=270007

If you have a <hr /> or an empty <div> before the "beginofsite" class, you might get spotty results. I am not sure if the same problem would arise if you have <hr /> or empty div after "endofsite".
EDIT TO ADD --- Yes, I just checked --- same problem if <hr /> or empty div comes directly after "endofsite".

As RbnJrg pointed out, I had to add a <p> with some *text* in it before the page-break-before , even if that text was only a non-breaking space. You could set font-size to .05em to make it virtually invisible. You could also play with the display: none, or visible: hidden; although I never tried those, they might work to hide that paragraph if you need it hidden.

The book in question is posted here in the library

Hope you can get it worked out.

I guess this is the reason. It just doesn't work mostly

No, doesn't work in calibre reader.
See my attached epub example. The class works, but not the page-break-after attribute.

Thank anyway!

Your sample works for me in the calibre viewer.

What version of calibre viewer and OS are you using?

[jhowell]

Make sure that the calibre viewer is not in flow mode.

AHH! Sorry, that it is. Yes, then, calibre works then too
Sorry.

Flow mode is it.
I guess the MoonReader is the same thing, there too, there is a flow mode, which I love, because I can set an exact position of reading. Not many reader can do this.

So I guess then either flow mode or (soft) page break (with css) possible.

Many thanks!

PS.: Calibre 3.48 on Mac (last working on 10.11) and the last 4.x (because of DeDRM) on Windows 10.

You can run Calibre 5.x on Windows 10 because DeDRM 7.1.0 is no longer a test version. But if you share databases between your MAC and Windows, then you do want to stick with 4.23 because Calibre 5 changes the database and 3.48 is not compatible. 4.23 is compatible with the version 5 database.

In real life, many ereaders don't support the page-break CSS.

If the break is "mandatory" for something like a chapter break, best to do like Turtle91 recommended:

New HTML file per chapter.

Chapter01.xhtml:

<h1>Chapter 1</h1>
<p>It was a dark and stormy night.</p>

Chapter02.xhtml:

<h1>Chapter 2</h1>
<p>The next day was horrifying.</p>

That will work everywhere.

- - -

If it's "optional" (like breaking before/after a diagram or poem, etc.), then you could still keep the page-break:

<p>This is a poem:</p>

  <div class="poem">
    <p class="stanza">The cows are green.</p>
    <p class="stanza">The cows are red.</p>
    <p class="stanza">The cows are blue.</p>
  </div>

CSS:

div.poem {
  page-break-inside: avoid;
}

Those that support it, great. They'll try to display the poem as one chunk.

Those that don't support it (the vast majority)... okay. Having the CSS there won't hurt, and in the future, as support gets better, your ebook will already handle it!

Thanks! Then I can switch on PC to the v5+
I dont share databases with Mac and PC, I even dont know how that works
I use calibre only to convert books or to DeDRM books
Reading books I do only on my phone with MoonReader.
It would be great if calibre could use the same books than my phone, which I backup on Google Drive but than I would need to use Google Drive Sync on my PC and Mac too, that I dont want.

Thank you Tex2002ans too for your explanations.
