First of all, this plugin is almost exactly what I/my client needed (minus responsiveness and a few minor things) so thanks!
Through CSS I was able to change/override the h3 and content sizes to what I need but when the print window comes up it is not styled correctly and everything is much too large.
I see that there is a .print class before everything and when using Firebug I can change it all perfectly. However, when I put it in my CSS, and even when I use !important, it doesn't want to override your default styles.
What am I doing wrong?
