Can't proceed past use-css-selectors-to-style-elements

The page will not let me proceed past this point, the code is 100% turning the h2 element blue, I ran it through a linter on VSCode and there is nothing detected as wrong. Here is what I have submitted and yet get the error: “Your h2 element should be blue.”

  h2 {
    color: blue;

Your code is passing for me.

If you have a dark mode extension running disable it for the curriculum. There is a dark mode under the profile settings you can use instead. If that isn’t the issue, try using a different browser (Latest Chrome or Firefox).

That makes sense, this should be included on the page somewhere because there seem to be a lot of people having the same issue!

I agree. We will most likely be adding a note about extensions at some point.
