XF 1.3 Alter text positioning in message elements


I've been fiddling around with the message elements a fair bit, however I'm unable to do exactly what I'd like to do with my limited knowledge of CSS and whatnot.
I made a crude image of how I'd like it to look, as it will explain what I want better than I can.


Obviously, the image on the left is what I currently have, and the image on the right is how I'd like it to be.

Thank you very much in advance!
