With this change, we reduce the amount of inline CSS used
for EPUBs. Almost everything is now in the default EPUB
CSS (`data/epub.css`), which can be overridden either by
putting `epub.css` in the user data directory or by using
`--css` on the command line. Inline styles are only used
for syntax highlighting (which depends on the style specified,
and is only included on pages with highlighted code) and
for bibliography formatting (which can depend on the CSL
style, and is only used in the page containing the bibliography).
Note that, for compatibility with older readers, we don't
use flexbox to style `column/columns` divs by default, as
we do in HTML. Instead, we use an older method which only
works when there are two `column` divs inside a `columns`
div. If you need more than two columns and aren't worried
about support for older EPUB readers, you can modify the
default CSS (there is a comment in the CSS telling you what to do).
Closes#8379.
Include abstract in default template.
Also ensure that the essential styles needed by
pandoc (`styles.html` partial) are included in the
templates. This is important for correct formatting
of CSL bibliographies.
Note that much of the styling in `styles.html` will
be ignored for EPUB, because of the conditional on
`document-css`, but if it is desired, you can set
the `document-css` variable.
In addition, the code generating the image has been moved
to the template, to make it more customizable.
Those who use custom EPUB templates will need to adjust their
templates, adding the code to generate the cover image.
(Previously this was just inserted into 'body'.)
Closes#5643.
instead of relying on CSS. Closes#4162. HTML-based templates have had
the custom CSS for div.line-block removed. Those maintaining custom
templates will want to remove this too.
We still enclose line blocks in a div with class line-block.
* Move as much as possible to the CSS in the template.
* Ensure that all the HTML-based templates (including epub)
contain the CSS for columns.
* Columns default to 50% width unless they are given a width
attribute.
Closes#4028.
We now issue `<div class="line-block">` and include a
default definition for `line-block` in the default
templates, instead of hard-coding a `style` on the
div.
Closes#1623.
All templates now include `code{white-space: pre-wrap}`
and CSS for `q` if `--html-q-tags` is used.
Previously some templates had `pre` and others `pre-wrap`;
the `q` styles were only sometimes included.
See #3485.
