Customising Nav for Mobile & Desktop

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

Hello,

I've created a hamburger menu for my desktop site and I need the type to be smaller and line height reduced so it fits on one page and matches the mobile version of the site. Does anyone have any pointers for code on how to do this?

Thanks

    font-size: 20px;
    margin-top: 10px;
    margin-bottom: 10px;
}
}
