Margin bottom ignored

[gregoriopellegrino]

I'm submitting a bug report.

Short description of the issue/suggestion: I am working on an EPUB file and testing it with Readium Desktop. In two cases the margin-bottom rule is ignored.

Steps to reproduce the issue/enhancement:

1. I can send with private email the EPUB file
2. I due casi sono:

HTML:

<header id="chapter-1">
      <h1>Title</h1>
      <p class="subtitle" role="doc-subtitle">Subtitle</p>
</header>
<p class="p">Text...</p>

CSS:

h1 + p.subtitle {
  font-size: 1.5em; /* x-large */
  font-style: normal;
  font-weight: normal;
  text-align: center;
  margin-top: -1.5em;
  margin-bottom: 2em;
  font-family: sans-serif;
}

HTML:

<p class="autore"><strong>Name</strong> bla bla bla</p>
<p class="autore"><strong>Name</strong> bla bla bla</p>

CSS:

p.autore {
  font-size: 1em;
  text-indent: 0;
  text-align: justify;
  margin-top: 0;
  margin-bottom: 1em;
}

Do you know which CSS modules (stylesheets) are impacted? No...

Please tell us about your environment:

• Platform: MacOS
• Browser / Rendering Engine: I think Chromium on Electron (Thorium v 1.4.0)

@gregoriopellegrino by any chance, do you have publishers’ styles disabled and paragraph margins set in advanced settings?

We discussed advanced settings during the engineering call last week and are aware that there are existing issues re. their management when they have not been set and we need a default.

I have the default settings:

I experienced the same bug, actually I could not find a way to insert spacing before or after an element. Anyone has faced the same issue?
