Links not working on Parallax design - html

Question

I have a link in the final div (slide4) and it is not working. I've messed around with z-index and positioning but that didn't work.
This is my first time messing around with a parallax design and I'm using a template to familiarize myself with it, but I hit a snag in this and can't figure it out.
Here's the codepen: http://codepen.io/anon/pen/bdGcI
CSS:
<style type="text/css">
html {
height: 100%;
overflow: hidden;
}
`body {
margin:0;
padding:0;
perspective: 1px;
transform-style: preserve-3d;
height: 100%;
overflow-y: scroll;
overflow-x: hidden;
font-family: Oswald;

</head>
HTML in question:
<div id="slide3" class="slide">
<div class="title">
<h2>Music</h2>
<p>words words words.</p>
</div>
</div>
<div id="slide4" class="slide header2">
Final Page Link.
</div>

Answer 1

Because :before pseudo class is causing an overlay over the content as you have written
.slide:before {
content: "";
position: absolute;
/*top:0;*/ /*remove this */
bottom: 0;
left:0;
right:0;
}

Answer 2

You have .slide:before with position:absolute; if you remove that it will work, so your problem is that Absolute position is Over the Link and content. If you add position:relative; to ahref or add relative to new Container inside #slide4, it will work..
