I’m always second guessing myself on this subject. I understand markup. Margin often tries to make my head explode. I found this Markup vs. Margin blog post over at Patriot Software to be very helpful and I bookmarked it. Pretty smart of this software company to make this reference available.

Nicely played Patriot Software.
