fn main() { // this list of used classes would ideally be parsed out of the written html, // but i don't want to over complicate this example let classes = [ "mt[10rem]", "color[#e20f00]", "color[green]hover", "content[attr(after)]$after", "content['*']$before", "color[red]$after", ]; let z = zephyr::Zephyr::new(); let css = z.generate_classes(classes); let html = format!( r#"

this text is red, but green on hover

this text has a lot of margin

"# ); std::fs::write("./examples/index.html", html).unwrap(); }
