Custom CSS for TXT -> EPUB conversion

[Dekker500]

Hi there.
I'm working with numerous documents which, for ease of mass-editing, I'd like to keep in .TXT format.

I have no problems converting them to EPUB format. Everything seems fine.

HOWEVER

I'd like to modify (or even replace) the default CSS that gets embedded into the .EPUB. When I use epub-convert with the --extra-css "blah.css", the contents are added to the "contents.xhtml" in a style block, but no-where else!

Is it possible to embed contents into the "stylesheet.css", or add a new "style.css" to be loaded alongside it, for the entire "book"? Maybe I am missing something in the command line arguments - ideas?

ebook-convert '.\input.txt' '.\output.epub' --formatting-type markdown --input-encoding UTF-8 --markdown-extensions=footnotes,tables,toc,smarty,nl2br --paragraph-type=single --epub-inline-toc --extra-css "./custom.css"

All style rules are merged and flattened during conversion. Including extra css. If you want to override the styles applied by the markdown input plugin give your custom css higher precedence, the most foolproof way to do that is by using !important in your css properties.

But that is what I don't understand...

I use the ebook-convert with the following arguments:

ebook-convert '.\Pathless Trail - Manual Edit.txt' .\PT.epub --formatting-type markdown --input-encoding UTF-8 --markdown-extensions=footnotes,tables,toc,smarty,nl2br --extra-css "./custom.css"

and the custom.css is thus:

.mytitle {
    display: block;
    font-size: 1.41667em;
    font-weight: bold;
    line-height: 1.2;
    margin: 0.83em 0;
	text-align:center
    }
.mysubtitle {
    display: block;
    line-height: 1.2;
    text-align:center;
    color:blue
    }

The conversion seems to happen OK:

Conversion options changed from defaults:
  extra_css: './custom.css'
  markdown_extensions: 'footnotes,tables,toc,smarty,nl2br'
  formatting_type: 'markdown'
  input_encoding: 'UTF-8'
...

but when I explode the .epub file I can find no instance of "mytitle". Where should it be located in the final epub file?

class names are not guaranteed to be preserved by coversion. Only final styles. Look for the styles.
