Need Help with Burger icon

Site URL: https://thesurfside.com/

Hi there,

I am having trouble finding the code that can change my Burger menu icon to an image icon that I have already uploaded to the Custom CSS area. I have a sun icon that I would rather use. 

After looking for a while, my template is named Brower. ID :5c5a519771c10ba3470d8101

Also- why can't I switch from templates to other templates? That seems like a fail on Squarespace's part. Please help! Thank you!

It looks like you solved with this CSS?

.burger {
    background-image: url('https://static1.squarespace.com/static/5f63aaae924d3f3c7351c8bd/t/602d87b80d012539eebf7690/1613596600778/burger+icon-03.png');
    background-size: contain;
    background-repeat: no-repeat;
    background-position: right;
    background-color: transparent !important;
    height: 60px
}

.burger-inner {
    display: none
}
