URL of experiment:
Description of the problem:
“cdn jsdelivr net” has been blocked in China since May 17, 2022. The CSS style has to be loaded before the online experiment started (see the “index.html” file content in the picture). Therefore, please change the source of the CSS to help us restore the online experiment, much appreciated.
I have completely solved this problem:
Change the index.html file in gitlab repository
Change the source of nmp by replacing the https://cdn.jsdelivr.net/npm/ to https://unpkg.com/, and other part remain unchanged.
Such as https://cdn.jsdelivr.net/npm/jquery-ui-dist@1.12.1/jquery-ui.min.css to https://unpkg.com/jquery-ui-dist@1.12.1/jquery-ui.min.css.
Than save the index.html file, the experiment runing again!
