I’m of two minds regarding your reply.
First is, that’s great I should learn some CSS. I would help me customize future things with the site.
The other reaction is that I paid you $60 for a theme that should have the footer alignment as a setting. Better yet it should be center justified to begin with. You could have instructed me how in the time it took you to tell me to go read your tutorial.
Being told to go learn something after paying is kind of offensive.
