Formatted Messages Customization

Can I customize the Formatted Messages control with a new Message and CSS?
If yes, then how?

Have a look at the CSS Style property on that control. You should be able to specify an inline css style(s).

there are no CSS style property (at least in the IDE)

I’m sorry. I skipped an obvious step. Please place a Block Panel around the Messages Control and supply style information on that panel.

Alternatively, if you want complete control over how the messages are styled, then you could use the ‘Output > Messages’ control instead and supply your own css styles there.
