What is the right approach for css file import?

[borsemayur2]

I'm getting TypeError: Cannot resolve module "file:///home/mb/my/career/deno/aleph/todos-app/.aleph/development/-/cdn.https://cdn.esm.sh/antd@4.13.0/dist/antd.css" error for direct import of https://cdn.esm.sh/antd@4.13.0/dist/antd.css. But the same file works (and styles are applied) if I save the code in public/antd.css/ and import from there.

Is that the right approach or is there any other way to import css files?
