Problem with Lanyon Theme for Github post

I’m a newbie to GitHub and have been desperately trying to have a good theme for my juypter notebook posts. I decided upon the Lanyon Theme so I forked it. When I refresh my page it has the content but the style is not there. I tried this thing with changing the base url to ‘\lanyon’ but it still doesn’t work. Anyhelp would be really appreciated.

The link to my repository is ‘https://github.com/psireal9/lanyon’ and you can find my webpage here ‘https://psireal9.github.io/lanyon/
