CSS editing extension breaks tests on CSS lessons

When using Dark Reader to change the CSS for contrast and readability, it breaks the CSS lessons in Responsive Web Design that check for color. This is far from obvious as the color is still a shade of red to the user.

I recommend either 1. allowing different shades for those lessons, 2. checking the code used instead of the style in the results or 3. do the tests on the server side. This issue has not only caused problems for users like me who use extensions but also to users on older browsers or on mobile.

The least that can be done is to warn users that tests are done locally, and that changing the environment (browser, extensions, platform) can help fix issues unrelated to the code produced.

Well, what you can do is change the main theme of FCC , because FCC already have a dark them on the settings

If you think it is a bug, you can report it as such (or as a feature request):

Thank you for helping make FCC better. Bugs can be reported as GitHub Issues. Whenever reporting a bug, please check first that there isn’t already an issue for it and provide as much detail as possible.
