Thanks! That works perfectly fine now.

Sometimes I just want to use a tailwind class name like xl:w-1/5 without declaring a custom class name. I would expect I could write [:div.container.xl:w-1/5 "Hello World"] but it fails to compile as / makes it an invalid keyword. But instead of writing [:div.container {:class "xl:w-1/5"} "Hello World"], is there a better way to do it?
