My CSS navigation menu isn't functioning in IE11, although it works perfectly in Chrome and Firefox. The menu is purely CSS-based with no JavaScript involved. I've tried playing around with doctype declarations but haven't been able to resolve the issue.
Can someone please help me figure out what I might be overlooking?
nav ul {
margin-top:1px; /* tucks the child ul up close to the parent li */
