Hi Ton
The current situation is that the stylesheet mechanism renders the tiddler
$:/core/ui/PageStylesheet into a special "fake" dom, and then extracts the
text and jams it into a <style> element in the DOM. The content of
$:/core/ui/PageStylesheet is:
<$list filter="[is[shadow]tag[$:/tags/stylesheet]]
[!is[shadow]tag[$:/tags/stylesheet]]">
<$transclude/>
</$list>
So, at the moment, you'll get all the shadow stylesheets first, and then
all the non-shadow stylesheets. That means that for the most part, if
you're overriding a style rule that is defined within a theme, then you'll
be able to rely on the stylesheet cascade, and won't need to worry about
devising more specific rules to force the override.
We may well still need to add a mechanism to give a finer degree of control
of the ordering of the stylesheets. At least that can be done by hacking
$:/core/ui/PageStylesheet, so anyone can experiment with alternative
arrangements.
Best wishes
Jeremy
