We have an old web app, which would be much more usable if it could be visually tweaked a bit. Being in a corporate environment - IE (always using the latest version) is all I can use. Also app in question being 3rd-party - there's no way to change it's own CSS files.

Is there a way to use per domain injected custom CSS in internet Explorer.

Let's say I want to change the background-color of domain http://oldapp.localintranet/ - is there any way to make this happen?

  • Place to put a custom.css-file?
  • With an add-on/extension?

@Prasad: Stuck with IE - can't use anything else. – Damiqib Dec 19 '12 at 16:07

Thank you. IE7Pro does the trick for me. – Damiqib Dec 24 '12 at 19:07

Do you have access to the application files? If so you can place a custom.css file after the last .css file in the header. CSS cascades and the last CSS styles/classes are ones which take effect most times. !important may be needed to override any inline styled elements or possibly some ID's.

You can override CSS for IE browsers only using condotional comments more on that here http://www.quirksmode.org/css/condcom.html

If you do not have access to the CSS files, you would need to use an add-on in the browser which would load your custom.css when you browsed http://oldapp.localintranet/ But then you'd have to account for some people using Firefox and Chrome.
