When Rheo generates HTML, it injects a default stylesheet into the generated static site for a simple, modern, and mobile-friendly aesthetic. ‘Screening the subject’ is a website generated with the default Rheo stylesheet for reference.
You can fully customize the stylesheet by adding a style.css at the root of your project directory. Note that if your project contains a custom style.css, none of the styles in the default stylesheet will be applied. If you want to build on the default styles, copy and paste the default stylesheet into the style.css file in your project directory.
