github - The blog built using jekyll displays correctly locally, but when it is transferred to git, the formatting is garbled when using gitpage.

Question

The website built locally using jekyll is displayed normally, as shown in the picture

But when I uploaded it to github and used gitpage, the formatting was garbled. I looked at the css below and it was not generated. I don’t know what the problem is, as shown in the picture

There are similar questions, but I didn’t solve the problem based on their answers. /q/1010000004165137

The direct reason is that it cannot be loaded css/main.css

The reason why it cannot be loaded is that the address he requested is
https://2youngg.github.io/css/main.css

https://2youngg.github.io/Test01/css/main.css

Solution
In config.yml, there is a field similar to base_url, which is set to
https://2youngg.github.io/Test01/
