Style sheets
A list of XSLT or CSS/SASS style sheets to apply.
Must be a space separated list of URIs, absolute or relative to the input.
Style sheets can also be associated with the source in other ways: linked (using an
['xml-stylesheet' processing instruction](https://www.w3.org/TR/xml-stylesheet) or a ['link'
element](https://www.w3.org/Style/styling-XML#External)), embedded (using a ['style'
element](https://www.w3.org/Style/styling-XML#Embedded)) and/or inlined (using '[style'
attributes](https://www.w3.org/TR/css-style-attr/)).
Style sheets are applied to the document in the following way: XSLT style sheets are applied before
CSS/SASS style sheets. XSLT style sheets are applied one by one, first the ones specified through
this option, then the ones associated with the source document, in the order in which they are
specified.
All CSS/SASS style sheets are applied at once, but the order in which they are specified (first the
ones specified through this option, then the ones associated with the source document) has an
influence on the [cascading order](https://www.w3.org/TR/CSS2/cascade.html#cascading-order).
CSS/SASS style sheets are interpreted according to [braille
CSS](http://braillespecs.github.io/braille-css) rules.
For info on how to use SASS (Syntactically Awesome StyleSheets) see the [SASS
manual](http://sass-lang.com/documentation/file.SASS_REFERENCE.html).

property
Table of contents: Table of contents depth
The depth of the table of contents hierarchy to include. '0' means no table of contents.
A table of contents will be generated from the heading elements present in the document: from `h1`
elements if the specified value for "depth" is 1, from `h1` and `h2` elements if the specified value
is 2, etc. The resulting table of contents has the following nested structure:
~~~xml
<list id="generated-document-toc">
<li>
<a href="#ch_1">Chapter 1</a>
<list>
<li>
<a href="#ch_1_1">1.1</a>
...
</li>
<li>
<a href="#ch_1_2">1.2</a>
...
</li>
...
</list>
</li>
...
</list>
~~~
Another one of these is generated but with ID `generated-volume-toc`. `ch_1`, `ch_1_2` etc. are the
IDs of the heading elements from which the list was constructed, and the content of the links are
exact copies of the content of the heading elements. By default the list is not rendered. The list
should be styled and positioned with CSS. The following rules are included by default:
~~~css
#generated-document-toc {
flow: document-toc;
display: -obfl-toc;
-obfl-toc-range: document;
}
#generated-volume-toc {
flow: volume-toc;
display: -obfl-toc;
-obfl-toc-range: volume;
}
~~~
This means that a document range table of contents is added to the named flow called "document-toc",
and a volume range table of contents is added to the named flow called "volume-toc". In order to
consume these named flows use the function `flow()`. For example, to position the document range
table of contents at the beginning of the first volume, and to repeat the volume range table of
content at the beginning of every other volume, include the following additional rules:
~~~css
@volume {
@begin {
content: flow(volume-toc);
}
}
@volume:first {
@begin {
content: flow(document-toc);
}
}
~~~

obfl-toc`](http://braillespecs.github.io/braille-css/obfl#extending-the-display-property-with--obfl-toc)
