css - Forcing content to not overflow to the right of the screen

Question

I'm trying to make all content of all websites in my browser to squeeze to screen width by userstylesheets. I'm stuck at making this work: https://developers.google.com/speed/pagespeed/psol

The content doesn't use my browser's horizontal scrollbar making width:100% selector useless. Any other options?

BTW in width:100% I'm assuming it's 100% of it's parent's width. How can I get 100% of screen width?

也许尝试摆脱这个

#gc-main {
  overflow: auto;
}
