sidebar under content issue

For some reason, my sidebar is below my content suddenly. I was editing POSTS when this happens, so it makes no sense to me. And I’ve adjusted the width and it doesn’t matter what i do, the sidebar is still floating under the content. And the footer is wonky. You will notice on the upper left of the footer are the facebook and rss icons that I was adding to posts. IDK where these rogue icons are coming from. I don’t know what I did, but I would really appreciate any help!
