There might be some things I had overlooked when overriding styles and it's not the prettiest, but it should be usable.
Please let me know if you find unreadable text or if you have suggestions for improvements. The best way to do that is by opening an issue at https://github.com/codewars/codewars.com .

I came to the forum for this issue too. Thanks for the github issue link. I really hope the fix is done soon.

Please see the post right below yours x)
You can try installing Stylish: https://userstyles.org/
And for codewars themes, there's a light theme.
