Well, if this one success, I may really cry out.
I mean, the previous ones I built were either only with the .github.io working or only have the post function.
Today and yesterday I've commited more than a hundred times and re-created the github page for idk-how-many-times.
All I want at the beginning was, just a place created by my own to post some articles I like; however, those attempts just didn't work :(
yeah, may be I am too dumb to deal with github, but I still got here : ) with some newly learnt HTML and git knowledge!

update: It's worked! Gosh! Credit to Hank Quinlan. Thank you so much! Many thanks to other guiders for creating your tutorials on github pages as well. I may not fully success on creating this site following your tutorials, but I also learnt a lot! That's also a kind of success, isn't it?
