Hi @Vishakraj! Thanks for creating this issue. I tried your solution and some thing like this actually worked for me. Here is the complete code:
import gradio as gr
css_code='body{background-image:url("https://picsum.photos/seed/picsum/200/300");}'
gr.Interface(lambda x:x, "textbox", "textbox", css=css_code).launch(debug=True)
Which produces this:
It could definitely look nicer with some more custom css, but it should work! This with gradio==2.9.1
