Here's my codepen: <http://codepen.io/Chiz/pen/MaBwBb>

When you click the buttons, usually the button will give a visual feedback of being "pressed down", but in this case, no such thing happens. It's like the buttons have been disabled. Why is this?

```js
$(document).ready(function() {
  $("#fullpage").fullpage({
    verticalCentered: false,
    resize: true,
    scrollingSpeed: 700,
    css3: true,
    easing: "easeOutBounce"
  });
});
```

```css
* {
  box-sizing: border-box;
}
html,
body {
  height: 100%;
}
div.container {
  position: relative;
}
#fullpage {
  width: 100%;
  height: 100%;
  background-color: #ffe4b3;
}
#header {
  width: 100%;
  height: 70px;
  line-height: 70px;
  background-color: #343434;
}
#header ul {
  list-style-type: none;
  color: white;
  margin: 0;
  height: 100%;
}
#header ul li {
  display: inline-block;
  float: right;
  padding: 0rem 2rem;
  width: 10rem;
  height: 100%;
  text-align: center;
  font-size: 1rem;
}
#header ul li a {
  color: white;
  text-decoration: none;
}
#footer {
  width: 100%;
  height: 50px;
  position: absolute;
  bottom: 0px;
  background-color: black;
}
.slide {
  font-size: 1.5rem;
}
.button-container {
  position: absolute;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}
.prev,
.next {
  width: 7rem;
  height: 3rem;
  font-size: 1rem;
}
```
