I've got an issue with responsive web design

hi I’ve got an issue with step 49 on the responsive web design certificate course.
I have completed the step roughly 30 times now and it is still saying its wrong I’ve googled the answer and got the same result I have also watched a video on YouTube showing the same response that I gave and it was correct. I just wanted to make sure there was nothing else that I’ve missed.

Please share your code and a link to the lesson.

If your code is correct, this could be a browser issue. Sometimes using a different web browser or updating your current one will solve the issue and allow you to pass the step.

ok great I will try this first and see if it works if not ill post a link thanks for your help
