CSS: Slider overlaps Drop down Menu on Mobile - Z-Index issue? - html

Question

Update:
I'm sure this will be easy fix for advanced members. I have created drop down menu with the 'nav' element. For some reason as hard as I try, I cannot get the menu to overlap the slider images below it when you expand it on mobile. I've tried lowering the Z-index on the slider and raising it on the menu. What am I doing wrong? Thanks in advance:
UPDATE: Here is a fiddle link as requested by a comment which includes the HTML. https://jsfiddle.net/wknow6cv/#&togetherjs=ADxkd31O6q

Answer 1

Maybe try to change the media queries nav to position: relative;
EDIT:
Try this instead, change the display: none to inline:
nav ul, nav:active ul {
display: inline;
z-index: 1000;
position: relative;
padding: 20px;
background: #6991AC;
right: 20px;
top: 60px;
border: 1px solid #FFF;
border-radius: 2px 0 2px 2px;
width: 50%;
}
