My pure CSS dropdown isn't working, anybody knows how to fix it?

Question

I'm a CSS starter and my pure CSS dropdown isn't working.

Example in this jsfiddle: https://jsfiddle.net/uevewfsy/

I've been looking around on internet and trying to fix it myself but I have tried countless things and it still isn't fixed. Having a float: left; on the primary ul seems to fix it, but then my nav isn't centered anymore.

Hope someone can help me so I can go further with programming again ;)

* {
    padding: 0;
    margin: 0;
    border: 0;
}

html, body {
    height: 100%;
    width: 100%;
    font-family: 'Open Sans', sans-serif;
}

h1 {
    font-weight: 100;
}

.nav {
    width: 100%;
    height: 10%;
    background-color: #333;
    text-align: center;
    position: fixed;
    z-index: 150;
}

.nav ul {
    height: 100%;
    width: 100%;
}

.nav > ul > li {
    display: inline-block;
    list-style: none;
    margin: 0 20px 0 20px;

.nav > ul > li:first-child > a:after {

    border-bottom: 1px solid white;
    border-right: 1px solid white;
    position: absolute;
    margin-top: calc(5vh - 5px);
    margin-left: 8px;
    content: "";

you are just missing vertical-align:top in your nav > ul > li,

you can add position:relative/top to your li/ul as well.
