[Solved] Image Display on Hover

Question

Your jsFiddle was messed up, that’s all. You shouldn’t put the <style></style> tags in the CSS area, and you shouldn’t put the <script></script> tags in the JavaScript area. Also, to include jQuery, you need to include it as an external resource, which is a section in the left sidebar. You put your resource URL in the text box, and click the plus button at its right. Here’s a fixed version, with your HTML cleaned up too.
