In Radiate I convert Flex UIComponents to HTML components and had this
problem. I made an option to allow styles to be defined inline or in a
style sheet. If the option was stylesheet then if the component had an id
the styles were declared by id. This included position, size, etc:
#myLabel {
style: value;
}
If the component didn't have an id too bad. I'd give it an id using Flex
naming utils class and again declare styles there.
But I added an option to let developers override the styles per component
and that might work here.
So you would have a components style declaration by id and then in Radiate
there is a user styles field. Any values in that field would be declared in
the style declaration but they would be placed at the end. Everybody knows
that last declaration wins, even grandma.
#myLabel {
style: value; /*define by framework */
style: newValue; /* defined by user */
}
You could also declare style: inherit and I think that resets the value.
Yes, the style is declared twice. Who cares. But yes to look pretty, I plan
to remove the first declaration or comment it out in a future update.
If Flex JS made some combination of class and class#id it might be an
option so that you can declare your own style declaration afterwards and
restore the defaults. Yes there might be two style declarations but at
least then they wouldn't be defined inline.
