I've thought maybe the reason the theme shows up when I am logged into my website but not when I am logged out of my website is because there is an error with my stylesheets. Here's how they currently read:
/* Welcome to Custom CSS!
CSS (Cascading Style Sheets) is a kind of code that tells the browser how to render a web page. You may delete these comments and get started with your customizations.
By default, your stylesheet will be loaded after the theme stylesheets, which means that your rules can take precedence and override the theme CSS rules. Just write here what you want to change, you don't need to copy all your theme's stylesheet content.
Do they need to be updated to show my theme regardless of whether I am logged into the admin panel?
