What makes code's border become white?( code is from my hexo blog article ,edited with markdown editor))

Question

I'm writing on my new blog, which was established by hexo (theme). I used cmd markdown editor, when I previewed blog article by chrome, just found that there was an unexpected white border around my code. Just like this: white border around my code line, and the border is quadrate (in the markdown editor, there were 4 or 8 spaces before "my code;"), look, the border is different from above

I'm new to javascript, this is my first question on stackoverflow, I want to konw how to fix it,and why other code is normal. I'm really grateful for your help.

my poor github aticle address: hellowor1d.github.io/2015/07/11/2015-06-11-JavaScript-function/
