Add colour feature and font size

[OrionRandD]

Hi, Could you add a colour feature to the webpage and a font-size feature as well? Thx.

[zhisbug]

what do you exactly mean by color feature and font size? for which part of the demo page?

@OrionRandD one can set it on the fastchat/serve/gradio_web_server.py

Is this still an issue for you? Perhaps we could close this one if it isn't.

Closing this as it's stalled.
