How do I condense my navigation so that it's only one line? (Other suggestions here don't work.)

How do I get my navigation bar to one line? I don't want to delete any text.

I tried the last option on this thread (https://community.shopify.com/c/shopify-design/how-can-i-move-my-navigation-menu-to-one-line/m-p/155... but I don't have "Asset->/base.css->" on the backend...

Here is a link to my site. Thanks!

You can try to add this code at the very bottom of your styles.css file and check again. 

@media (min-width: 990px) {
    .site-control.nav-inline-desktop .site-control__inner .nav-row .tier-1 { padding: 0 !important; }
    .site-control__inline-links { flex: 12; }
    .site-control .site-control__inline-links a { 
        font-size: 16px! important;
        padding: 1rem !important; 
    }
}
