Previously, when you had to edit you theme or one of your plugins with a CSS hack, the code was usually placed in the theme stylesheet file (style.css) file or possibly in a child theme. I just discovered what, to me, is a better solution. The My Custom CSS plugin allows me to place all my code hacks in one place!
Find and download the plugin, activate it and now you have one place for ALL YOU CSS TWEAKS! Easier to print, easier to find and eliminates the possibility that a theme update will blowup you custom CSS!
