Custom Stylesheet & Script

Doesn't seem to work at all in Opera GX, July 2023

It just works as advertised. No useless fireworks. You add CSS, JS code and it injects it into web page. I use it to nuke annoying top banners in Google docs published to web. Also to override eye killer dark theme on YouTube with my own that does not destroy my eyesight and does not create head splitting headaches..

Thank you to the developer, this is a really useful extension and the additional source references with examples are appreciated.

No longer seems maintained and could not get to work even on simple pages.

I had a very simple thing to style, because a site design was bugging me. This was the only extension I tried, and it worked right away. Easy. Thanks a lot!

It's been working very well for me for quite some time now (on Mac and Windows systems alike): I can finally read most Web pages without eye strain.

Very useful

Seems to work, to an extent. Is there any way to have the JS fire after the page DOM has loaded? At the moment it seems that many getElementById commands won't work when used in this extension.

needed a simple css rule for a service I use. Installed the extension, added the rule, now my life is much easier.

Works fine, although not site specific. Save/Revert buttons would be nice.
