In the module settings, look for the option to "display container" and remove the tick from the box.

lol yeap, Its a preference I use transparent containers as well but its mainly because I prefer to get a better feel for what my site will look like without having to toggle to view mode. Not sure which is more work though. :)

One thing to note though that if you have special spacing from the container like extra padding / margins. if you remove the container it can sometimes alter those. Other then that a little check mark does wonders.
