[pmwiki-users] How does Q:-markup feature really work?

[SteP]

I just don't get it. I've looked at the HTML and CSS code that PmWiki outputs for the Q: (question) markup, 
and I can't spot anything that makes it render a dropcap, all I can see is that for "Q: some text" PmWiki 
generates <p class="question">some text</p> and no special CSS styles. So how does the magic work? 
'Cause I can see a dropcap indeed! Also, I would like to change the color of the dropcap from black to 
something else, but I can't find a way to do it. It's a mistery to me. Please someone shed some light before 
I get insane.
