Adding left and right columns to Yoko 1.0.5

I’d honestly recommend trying out a different theme that better suits your needs if you don’t have any coding experience. WIth this theme you actually do have a footer. I’m not sure about the theme’s options but you can always open up the footer.php file (either through an FTP client or in Appearance > Themes > Editor > footer.php (for that theme) and play around with it there.
