[ale] [OT] Stylesheet question

[Kevin O'Neill Stoll]

From: http://www.w3.org/TR/REC-CSS1#class-as-selector
"Only one class can be specified per selector. 'P.pastoral.marine' is
therefore an invalid selector in CSS1. (Contextual selectors, described
below, can have one class per simple selector)"

I belive I understand what you are trying to achieve, which is re-use of
code? The logic you are trying to implement makes sense to me, I have
wanted to do that many times. Unfortunately, you can inherit implicitly
but not explicitly. 

As the example shows, http://www.w3.org/TR/REC-CSS1#inheritance, if you
define an element inside of another that has a styling, that element
inherits the style.

Otherwise, I guess you are left to defining multiple classes to do the
same work or just define your stylesheet based on elements, e.g. -
P.style, H1.style.

So have one style for regular Paragraphs P{ color:red; } and then another
for your class P.style{ color:white; )

Hope that helps.
