Thanks! Yes you can use any valid CSS, see our styling docs: https://pynecone.io/docs/styling/overview. We don't have CSS classes, but you can copy your properties into our snake_case version and pass them to your components.
Thanks. I read the overview and what looked like the lack of support for existing CSS framework and stylesheets prompted my question.
Unless I'm misunderstanding how CSS support works here, I think this is a deal breaker for me at the moment. Being able to include external stylesheets/frameworks is something of a must have.
Appreciate it is Alpha level software so look forward to learning how the project evolves.
