Change button text-type

How do I change the text-style in normal buttons that you can put in?
For example I want my text inside that button to be bold. How do I do that?

The simplist way is to use an image button, instead of a regular button.

However, one other option is the "Set CSS" under appearance, since the text is rendered HTML5. You can use all of the properties here:

Thanks!
For anyone who wants to know how I did it I simply made:
Every tick > Button - set css style "font-weight" to "bold"

Just gave it a try.

Turns out, the setting sticks, no need to do it every tick. On object created/layout loaded, etc works just fine!

Cheers and thanks!

Yeah, obviously :P Just put it in every tick since I already had an every tick event, felt unnecessary to create a "on start of layout" event just for it ;)
