Dropdown Menu Design

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

Hi! I have a dropdown menu that is incorporated on my mobile and online website (more important on mobile) and wondering how I can change the design of the style of the dropdown menu? The text is currently too close to each other and too small on both mobile and computer. It would be hard for our clients to read it and I can not figure out how to change the style of the text spacing and size. Any help and advice would be greatly appreciated! I know you all are very busy and working on your own websites, so thank you in advance for any assistance! 

Add to Design > Custom CSS

a.Mobile-overlay-folder-item {
    font-size: 30px;
    margin-bottom: 20px;
}

Thank you so much, you're the best!
