7.1 Mobile Screen cutoff

Site URL: https://photoguy.com

Hello.

I did search but didn't find my answer in regards to 7.1 navigation menu as the screen is reduced for smaller devices.

In wordpress I was able to adjust the cutoff parameter for the screen size reduction for mobile devices. With my Squarespace 7.1 site, as the screen width is reduced, the header navigation starts to create a second line....which looks terrible. I attached an image to help explain my situation. Is there CSS or a setting that I may have missed in the Squarespace settings?

Thanks.

Add to Home > Design > Custom CSS

.header-nav-list {
    flex-wrap: nowrap;
}
.header-layout-nav-right .header-nav-item:not(:first-child) {
    margin-left: 1.2vw;
}

Thanks that helped. It's still wrapping onto the 2nd line. See the down arrow and the social icons? Anyway to fix that, or should I just get rid of those? I appreciate the help.

Is there a way to adjust the cutoff point? as the width comes in, I could adjust the point that it switches from the desktop menu to a burger style?
