CSS Code to change mobile navigation to hamburger in Avenue Template

Site URL: https://www.missjesscraven.com

Hello squarespace world, 

I'm looking for custom css to add that will change my mobile navigation from MENU to the hamburger icon. I found this:

/* HAMBURGER NAVIGATION */ #mobileMenuLink a:after { content: '☰'; color: black; width: 100%; text-align: right; position: absolute; top: 0; left: 0; }

But that just added a hamburger icon in the top right corner but didn't replace or change the current menu on mobile view.

Thanks!

Hi. Remove above code & add this to Design > Custom CSS

/* Menu to burger */
/* burger icon by iconmonstr */
#mobileMenuLink ul>li.active-link {
    visibility: hidden;
}
#mobileMenuLink ul>li.active-link a:before {
    visibility: visible;
    content: "";
    background-image: url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIyNCIgaGVpZ2h0PSIyNCIgdmlld0JveD0iMCAwIDI0IDI0Ij48cGF0aCBkPSJNMjQgNmgtMjR2LTRoMjR2NHptMCA0aC0yNHY0aDI0di00em0wIDhoLTI0djRoMjR2LTR6Ii8+PC9zdmc+);
    width: 30px;
    height: 30px;
    display: block;
    margin-right: 5px !important;
    background-position: right center;
    background-repeat: no-repeat;
    float: right;
    margin-top: 5px;
}
