How to request a root resource?

Question

css

Hello, I launched the server, it reported, please tell me how to request the root resource in the page?

Answer 1

I took a quick look and couldn't find the .modal-backdrop, either in the code or in the DOM... Maybe that's why it doesn't work?
In general, what is meant by the .modal-backdrop special area?
The patch that solves this problem is there: codepen.io/anon/pen/LGBPyv

Answer 2
