Hide Tag Cloud on Posts

I am building a new web site using POP Rock and the tag clouds are appearing on all posts. This serves no purpose and I want to hide the tag clouds. On other themes I have used I can simply turn the tag cloud off with a set up button to keep the could from appearing. For Pop Rock, I have tried adding various code to the ADD CSS function in the Themes > Appearence > Customize > Add CSS and nothing works. Can you share the appropriate CSS code and where it should be placed, i.e. header or footer? I have spend hours on this and would like not to have to switch to a new theme. Please help.
