Adding Conditionals in CSS Files (e.g., custom.css)?

[GrooveOnBeat]

As I add conditionals in the HTML templates, is there a way to add those conditionals in the CSS files?

Or conditionals can only work in HTML templates?

Yes, you can use logic in CSS files

I must have done it wrong then.

So something like this should work?

{{if \IPS\Dispatcher::i()->application->directory == 'forums' and \IPS\Dispatcher::i()->module->key == 'forums' and \IPS\Dispatcher::i()->controller == 'forums' and in_array(\IPS\Request::i()->id, array(1,2,3))}}

Ah, no, that won't because CSS files are compiled down when saved, so you can't write logic that depends on anything happening per-page. You can do something like this:

{{if theme.rounded_photos}}

...for example.

Let's say I wanted to call up CSS classes based on the page, member, member group, etc., am I then restricted within templates or blocks?
