In github, can you use Jekyll layouts from your user pages in your project pages?

I you have a github account with Jekyll-rendered pages at:

username.github.com

is it possible to use the layo开发者_如何学编程uts from there to also render your project pages at:

username.github.com/projectname

If so, how?

Yes, and no. You can use the layouts to render files in the projectname path of your username.github.com repo. If, however, you put the pages into the projectname repo, that repo will not have access to the same layouts unless you copy them in.
