Everything seems to be working well with the navbar initially, but when resizing the screen to a smaller resolution, all the navigation items disappear and the "hamburger icon" fails to appear.
<nav class="navbar navbar-custom navbar-expand-md fixed-top">
<div class="container">
<a class="navbar-brand" href="/home">
<img src="images/girlsinthegame.png" width="10%"/>
</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#mydropdown">
<span class="navbar-toggler-icon"></span>
<span class="navbar-toggler-icon"></span>
