Mobile drop down navbar - html

Question

I cant figure out for the god of me how to get my navbar to show in mobile. I'm not using bootstrap since I already built my own style and when I use bootstrap it conflicts with what I have already made.
I'll paste the css of the menu im using and for mobile portion

If you want to do it just with css:
<!DOCTYPE html>
<html>
<head>
<style>
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content a:hover {background-color: #f1f1f1}
.dropdown:hover .dropdown-content {
display: block;
}
.dropdown:hover .dropbtn {
background-color: #3e8e41;
}
</style>
</head>
<body>
<div class="dropdown">
<button class="dropbtn">Dropdown</button>
<div class="dropdown-content">
