Seeking assistance to resolve a display issue with the inner div on this website. The problem occurs in Firefox but not in Safari or Chrome. Here is the code on jsfiddle. As a beginner in web design, I might be overlooking something obvious and have been unable to find a solution online. Any help would be greatly appreciated.
