Change default CSS of Google Chrome
How do I disable CSS or make my own CSS style for a specific website in Google Chrome?

Web sites like Wikipedia that extend to the full width of the available screen are very annoying when used with a big monitor.

How can I customize their appearance (for example, by injecting some CSS) in Chrome?

  • Fun, fixed width sites used to make me feel like wasting money for having a wide enough monitor. But monitors are getting really too wide nowadays. – LatinSuD Sep 24 '11 at 22:49

    None of those marked as a duplicate answer this question. The "default CSS" is not a specific site but browser wide. The second link is marked as a duplicate of the first and was not given any useful answers. – Danny Staple Dec 15 '16 at 14:49

Chrome supports greasemonkey style user scripts by default. Read this for more info - http://www.chromium.org/developers/design-documents/user-scripts

  • There are also variants, for chrome, Tampermonkey and Violent monkey, they have good score on the chrome addon site. – Quidam Dec 15 '16 at 6:17
