The main div for GitHub and Zhihu is too narrow, which makes my high-resolution screen not that useful. In this case, I update some exiting stylish script to improve.
You can download the stylish here, and import it to stylus.
BTW: I have some some hard-coded style for my 2560 x 1440(or similar) screen. I also fix the style for github home page.
Another improve for github - add personal&star links in head menu
This is a tampermonkey script, which can be download here.
(This is also a modified version from existing one, thanks for the good work from open source contributors)
