Basic CSS portion of Tutorials is Broken and Unusable

Tell us what’s happening:
I have been going through the modules of the responsive web design certification, and as soon as I got to the section: Basic CSS: Use CSS Selectors to Style Elements it stopped working completely. Everything past this and including this, does not work. The problem lies in the checking system. I have looked at my code a thousand times, and I know its correct, yet the checker believes that something hasn’t happened that has. For example on this tutorial, I was supposed to change the h2 element to blue, which I have, and it is reflected in the web page to the right, but when I check it, it says I still need to make it blue. Because following tutorials compound the code from previous ones, all the other checkers in further tutorials also do not work. I can no longer see if I am still doing it correctly because moving on is trusting that my first attempt is correct. Please let me know if there is a phone number I can call about this, or an email account I can get in contact with, because this is very important to me and I would like to finish soon.

This is an image of the web page confirming that the h2 element is indeed BLUE!!

Your code so far

Challenge: Use CSS Selectors to Style Elements

Link to the challenge:

It looks like you may be using browser extensions which are interfering with the CSS on your page. If your extension changes your CSS (such as adding a dark mode), then the test suite can’t verify that your CSS is correct. You need to turn off any extensions, such as a dark mode.

You can turn on the FCC dark mode in your options.

I thought I would post the checker error as well to help anyone try to confirm why it isn’t working:

remove the dark mod extension you are using, it is interfering.

you can turn on the native dark mode from the setting.


Wow I hadn’t thought of that at all considering it was still blue. Thanks guys.
