Code Not Working even though code is correct

I know my code is correct on the dashboard because I’m seeing my code change as per each lesson in real time but for whatever reason, my coding camp will not let me proceed to the next lesson even though I know my code is correct:

The Lesson Name: Applied Visual Design: Set the font-size for Multiple Heading Elements Passed

I’m not sure if it’s my browser I don’t know please help if you can. Thanks!

you always need to include your code and challenge like
we are not seers, or mind readers
