Sidebar background

How to change sidebar background? Thanks

Are you using the free or paid version? Free version has less customization options available.
Have you a screenshot of your blocks to show?
Did you check the blocks available and experiment with them?
Have you read the extension’s thread and especially the first post?

Sorry about the tone of my reply, but you have created 3 different topics with questions about the same extension. In my point of view such topics are spam.
Why don’t you just gather all your questions in one topic?
As you have already seen from the other posts you created help is available but there are some rules in the community.
