How to get Calibre to remove forced fonts and spacing

Ned · 06-20-2019, 03:47 AM

I've just got a Kobo Aura H2O and am using Calibre simply to store and put epub books on to it. I don't know a lot about Calibre yet.

One book I put on the Kobo seems to have some font and line spacing instructions built in so that it ignores my Kobo's attempts to change fonts or adjust line spacing. It allows me make the text bigger or smaller but that's all.

I was hoping that there were some settings in Calibre where if I just ran an epub to epub conversion it would take all this stuff out and let the Kobo change fonts and line spacing.

I don't want to edit stylesheets book by book if I can avoid it.

Are there any such settings please and if so what are they?

I think you are looking for a magic bullet and I don't think one exists.

The fact that your device balks at doing typical overrides, leads me to believe that something 'tricky' was done or you have a fixed layout book.

I gave up trying to use CONVERSION to fix layout issues a long time ago and use the editor almost exclusively. It can be lots faster in many cases and does not change anything that you did not do yourself

.

HTML and CSS (as used in ebooks) is fairly easy to understand. IMHO understand the 'Box Model' first, because everything on a page is really boxes within boxes (A paragraph is a box. A Span is a box within another box. Some parts of the box may not be active, but they are still there: like border:0, padding: 0.)

thanks for the reply theducks. Yes I was looking for a magic bullet, so at least I know there isn't one

Editing it is then!

I just used edit, removed the stylesheet and it's all Hunky Dory now

OMG

That was brutal (even if it did get the job done)

The traditional way, is to adjust values and attributes
