It's advertising, it happens every now and again, but if 你 have AdBlock it will only be black no ads, but if 你 don't there should be an ad for something.
the image shows an ad from about 6mponths 以前 (there have been 更多 though)
It's an advertisment for Lexus convertibles! You're probably seeing black because 你 have the ad blocker program, I don't. 潮流粉丝俱乐部 does full page advertisment some times, it's happened before. It will retreve to it's regular white backround in a couple days 或者 so.
