to apps.css.
If you add a new class with semantic meaning, document it below, under
-"Custom classes".
+"Custom classes", and be sure to explain it to the reader at
+_manual/01_welcome-to-ardour/02_about-ardour-documentation.html.
2. Format and Validation
use for potentially dangerous situations involving data loss, malfunction,
or sound quality issues. Currently rendered in a red box.
+.mac, .lin, .win:
+use as additional classes to mark a section as relevant for these operating
+systems only.
+
Check _manual/01_welcome-to-ardour/02_about-ardour-documentation.html, it
serves as a style and markup guide.
Every snippet of text should be enclosed in a block level element. The
default choice is <p>, the plain paragraph.
+<a>
+Cross-reference links in the manual are reasonably stable, since they are
+independent of the ordering number (which gets removed from the URL) and the
+pretty page title (the URL is created from the file name). So unless a file
+is renamed or moved to another sub-directory, links should be ok.
4.1 Inline markups
------------------
On each page, use only for the first occurrence of every abbreviation. Avoid
a redundant explanation in the text - the expansion can easily be extracted
via CSS for printing.
+Use only in the text body, not in headings.
<em>
is used to emphasize a word. Commonly rendered as italics.
------------------------------------
<kbd>
-Any keys or key combinations, mouse buttons, or controllers should be marked
-with this element.
+Any keys or key combinations, mouse buttons or controllers, menu items or
+textual user input should be marked with this element. It is used here in
+the widest possible sense, qualified by classes.
E.g.:
"Press <kbd>F</kbd> to fit all tracks to the height of the Editor window."
"Move <kbd>Fader 1</kbd> on your MIDI controller to bind it.
See above for other <kbd> classes to denote menu items, selections, mouse
events and controller actions.
+Keys and mouse key names should always be capitalized. We do not need to
+distringuish between "x" and "X", because the latter would be "Shift-X".
+In case you forget, the stylesheet takes care of this.
+
+CSS Classes used with <kbd> are:
+.modN
+.mouse: mouse buttons
+.cmd: a command line
+.lin, .win, .mac: add nice prompts to that command line
+.input: inline text to be entered by the user
+.menu: path to an Ardour menu or other GUI item
+.option: path to an option, with (X) at the end.
+.optoff: path to an option, with ( ) at the end.
+.button, .fader, .knob: external controllers (OSC or MIDI).
+
<code>
is only used for program code, or the content of configuration files etc. Do
not abuse to style keys or user input, use <kbd> instead.
The image tag must contain a 'src="/images/yourimage.png"' element and a
descriptive 'alt="A short textual description of the image content"'
element.
+Images are usually placed as block-level elements, i.e. outside of a
+paragraph.

+editors know where there's work to do.
