Calibre default CSS to <body>

heitormsilva · 11-23-2017, 09:32 PM

Converting from EPUB to AZW3 Calibre is generating the following CSS to the <body>

Code:

.calibre {
    margin-bottom: 0;
    margin-top: 0;
    padding-left: 0;
    padding-right: 0
    }

The resources/template/html.css is blank and the value of "Convert settings -> Page setup -> margins" are set to less than 0.

What else could I do to prevent this to happen?

Nothing, body margins are always set to zero so they dont interfere with page margins. You dont want body margins in an ebook, they make no sense.

Please, don't get me wrong, but I just can't get used with a piece of software imposing its patterns. It sounds a kind of dictatorship. I just think that the choice should be let to user.

Every software in existence imposes choices on the user. The very act oc creating software means imposing choices on the user.

Well, last time I looked (but it's been a while, so things may have changed) it did make sense to set the left and right margins as body margins, because setting them as page margins made ADE page numbers collide with the text.

I always start every css with:

Code:

* {
margin: 0;
padding: 0;
}

to get rid of any possible default margin settings.

Although I never use page numbers, I always DO use a body margin of 1% to keep the text from colliding to the e-reader display sides, hence allow a better reading experience. Further margin needs are set, where appropriate, with <p>, <blockquote>, etc.

Just my 2cts...

Why do you read with ADE right margin page numbers turned on?

Using a % for margins is a really bad idea. Don't give such advice to others. Using a % means things change based on what screen you are reading with. Your margins will be different reading on a 7", 6", 5" screens. Better to use a margin of 0 given that you have a Kobo. You can just use the margin slider to change the margins.

Advice can be ignored or taken: I never enforce my meaning (like some people seem to do).

And that is exactly what I intended. In proportion with the screen format. So, what is the point?

Well, not everybody uses a Kobo.

I'm confused, my body margin (always <body class="calibre">) is set by default in calibre is 5pts.

Code:

.calibre {
  display: block;
  font-size: 1.25em;
  line-height: 1.2;
  margin-bottom: 0;
  margin-left: 5pt;
  margin-right: 5pt;
  margin-top: 0;
  padding-left: 0;
  padding-right: 0;
  text-align: left;
}

My page margin set by default by calibre as

Code:

@page {
  margin-bottom: 5pt;
  margin-top: 5pt;
  }

When I change the the values in page setup and mark Left and Top unchanged the Page top remains unchanged, the Body left disappears. Yet when I change the Right and Bottom to 15pts the body right and the page bottom both change to 15pts.

Something seems inconsistent.

Because they can not be turned OFF in the version on the device.

Exactly. Actually, I do turn them off, but when I make a book I also think of devices on which you can't do that.
