Ok. Will do. It's not so important, because if I want colorful style, I just use the html. But I was put off that nothing I do to the output css seems to do anything, I can't so much as choose a bigger font-size or color for epub. Not just that, but I can't afterward change the css with calibre's editor or sigil if I tried, so I thought I must be messing up and wanted to ask. If it's default, no problem.
This is my epub style:
Code:
##style:
titlepage_use_table: true
wide_titlepage_entries:storyUrl,authorUrl,seriesUrl
output_css:
body { margin: 2%%;}
pre { font-size: x-small; }
sml { font-size: small; }
p {line-height:170%%; }
blockquote {padding: 0.5em 0 0.5em 0; margin-bottom:1em;}
a:link {color:#6495ED;}
a:visited {color:#333; font-style: italic; text-decoration: none;}
a[title] {text-decoration: underline; font-style: italic;}
td {height:2em; vertical-align:top; padding:0.6em 0.2em 0.4em 0.6em;}
br {margin:5px;
line-height:1.7em; }
h1 { text-align: center;
padding:1.5em 0 1.5em 0; }
h2 { text-align: center; color:#6495ED;
padding:1em 0 1em 0; border-bottom: 2px solid; border-top: 2px solid; margin-top:3em; }
h3 { text-align: center; color:#6495ED;
padding:0.5em 0 0.5em 0; }
h4 { text-align: center; }
h5 { text-align: center; }
h6 { text-align: center; }
.CI {
text-align:center;
margin-top:0px;
margin-bottom:0px;
padding:0px;
}
.center {text-align: center;}
.cover {text-align: center;}
.full {width: 100%%; }
.quarter {width: 25%%; }
.smcap {font-variant: small-caps;}
.u {text-decoration: underline;}
.bold {font-weight: bold;}
include_images:true
never_make_cover: true
Weird. Seems color change is not a problem anymore.

But everything else still won't work. Specifically, font-size and borders. It's no problem if some styles just can't apply, but I think it's more the case that I messed up.
Re: AO3 extra series. Sorry. I'll give an example link for the series thing:
http://archiveofourown.org/works/748503
This fic from the archive is part of two series. Attached is the epub output from fanficfare. I have serieshtml on second row usually. But this one for example is part of 2 series, so I also want both series in addition listed and linked after or right before the summary the same way and can't do it.
