[External] : Re: CSS Lookups and their origins (possible regression)

[Andy Goryachev]

If your stylesheet defines the necessary variables, the "users" should be able to redefine them, correct?

Or maybe allow for programmatic control of the stylesheet, similar to
https://github.com/andy-goryachev/AppFramework/blob/7f74f58ecd4de239be923c4384e10142e48ade7c/src/goryachev/fx/FxFramework.java#L31
https://github.com/andy-goryachev/AppFramework/blob/main/src/demo/appfw/Styles.java

Alternatively, we would need a new public API to allow you to do what you want how you want.  Perhaps if you could tell us about the problem you are trying to solve, exactly, and the APIs that are missing.

Correct. That's why I agree with John and why the current behavior is likely undesired. :-)

Hi guys,

I agree with John Hendrikx on this.

The thing is not that you override the "css variable" value but that you end up overriding the priority of the rules in Modena which the developer won't likely want to.

One other thing I'd add is that developers also like to use css themselves. If modena rules suddenly start to have the priority of AUTHOR this becomes much harder. They have to make their rules always more specific than Modena's that now have increased priority besides the fact that they need to be aware that this is actually happening and is the problem (in my experience many developers won't know this).

On a related note, I created a theme called JMetro. When implementing it I made it so that it was composed of author stylesheets (there wasn't a way to set it as a user agent stylesheet back when I started). That's also how 90% of themes work.
However this is an issue as developers wanting to override styles set by JMetro will have a hard time figuring out how to make their rules specificity in their CSS higher than JMetro's so they get overridden (I've had complaints on this). That's why now in the new theme I'm creating I'm setting everything to be an user agent stylesheet.

Thanks,
