How to distinguish timestamps in CSS?

How to distinguish timestamps in CSS?

[Sébastien Vauban]

Hello,

A quick (but not easy?) question about the Org publish to HTML and CSS: I
would like to make the 3 different timestamps stand out with different
backgrounds.

Is it possible with CSS?  I have the impression that it currently is not,
but...

This is some sample output in HTML:

#+begin_src html
<p><span class="timestamp-wrapper"> <span class="timestamp">2010-11-13 Sat</span></span><br/>
<span class="timestamp-wrapper"><span class="timestamp-kwd">SCHEDULED: </span> <span class="timestamp">2010-11-15 Mon</span></span><br/>
<span class="timestamp-wrapper"><span class="timestamp-kwd">DEADLINE: </span> <span class="timestamp">2010-11-20 Sat</span></span><br/>
</p>
#+end_src

Best regards,
  Seb

Hi,

Only partly.

You can distinguish between timestamps with and without a keyword. The 
following will set a red background on SCHEDULED and DEADLINE 
timestamps (sorry for the noise if this was clear to you already).

#+STYLE: <style>.timestamp-kwd + .timestamp {background-color: 
red}</style>

But you cannot distinguish between different keywords -- no CSS 
selector works on text content. You could use Javascript.

Yours,
Christian

Perhaps it'd be possible to (optionally) add an "id" selector to the timestamp
<span> elements and use that for CSS manipulation, tied to an org-mode ID or
some other unique id? Or perhaps just postprocess the HTML output to add such
ids.

Or make the HTML export add a timestamp keyword specific class to the
timestamp keyword span element.  So you could use:

#+begin_src css
.timestamp-kwd-scheduled + .timestamp { color: red; }
#+end_src

Cf. http://www.w3.org/TR/CSS2/selector.html

I recorded a WISH for this in the issues file.

Hi all,

Thanks Christian for info about this "plus" selection -- I totally ignored it.
Thanks for enlightening me.

I guess that'd be the way to go. In fact, I envision more than a color
background: I'd wanna use an image background. Something like:

    ,----------------,
    | DEADLINE       |
    |----------------|
    | 2010-11-15 Mon |
    `----------------'

just below the heading.

Working a bit more on my CSS (that should become a PROP for Worg3.css), I
envision as well a nicer "calendar icon" for the dates (a priori, inactive
timestamps telling when the meeting took place or when the note was taken):

      ,------,
      | Mon  |
      |------|
      | Nov  |
      |  15  | (in bigger size)
      | 2010 |
      `------'

That could be placed on the left, in the margin, for example.

But, to be able to do such a thing, we would even need the different
components to be selectable:

- year
- month
- day
- day name

Best regards,
  Seb
