@kylewu oops, I know what's your mean by, seems you will always use site.url to render anchor. All I worried about is virtual pah.
To clear more, I wanner to make sure we are discussing the same thing:
* Make sure the current GH page url is [http://stephanieyr.github.io/stephanie_jekyll](http://stephanieyr.github.io/stephanie_jekyll), not [http://stephanieyr.github.io](http://stephanieyr.github.io).
* Deploy current site to personal GH page([http://stephanieyr.github.io](http://stephanieyr.github.io)) and GH project page([http://stephanieyr.github.io/stephanie_jekyll](http://stephanieyr.github.io/stephanie_jekyll)) needs *different configuration*, otherwise the anchor link will point to wrong place....

If you mentioned upon two point, things will be interesting, and I eagerly want to know more information if I was wrong. :-P
Thank you.
