Hamburger Menu on Desktop Customization

Site URL: https://earthworm-clownfish-cc5d.squarespace.com/

I am having difficulty aligning my hamburger menu text to the left, and making the font size smaller.

Here is the code I am using to populate the hamburger menu:

//hamburger menu on desktop//
.header .header-burger{display:flex} .header-nav, .header-actions {display:none} .header--menu-open .header-menu { opacity: 1; visibility: visible;}
.header .header-burger{display:flex}
.header-nav, .header-actions {display:none}
.header--menu-open .header-menu {
opacity: 1; visibility: visible;
width: 35%; 
margin-left: 65%;
box-shadow: -5px 5px 15px #000}

There is a LOT of CSS on this site that we didn't do, I can provide that if needed.

.header-menu-nav-item a {
    margin: 3vw 1vw;
    font-size: 30px
}

Play around with those numbers to your liking. I made the text alittle smaller and moved towards the left.

Let me know if you need anymore help.
