[FeatureRequest] Inject style.css

[ikrum]

Background

I wanted to run the the built in server. But I need to add 10 lines of css code and adjust the appearances. I would be nice to have such feature that would add additional css into the server or maybe in the build as well.

Current Command

docgen server -f input-postman-collection.json -p 8000

Proposed Command

docgen server -f input-postman-collection.json -c style.css -p 8000
