I added the topic of this post to the title, a title like "hello", "help", or "a question" doesn't help others understand what you are talking about, and asking a question or introducing a topic at a first impression makes it that little bit easier for people trying to help. This (and other recommendations and advice) is also stated in our discussions guidelines.
You need to tell the wiki where the end of a box is. You do that using a closing tag; in this case, </div>. Usually we prefer links to the page with the issue rather than just screenshots but, in this case, the image alone shows you already have multiple unclosed boxes just in the first part of your page.
