I am having the exact same problem. Have even copied and pasted your code above to ensure, and it still says the same thing..
Not letting me move on, says i need to add a style when it's there
Have you checked if your browsers zoom is set to 100% ?
If so then paste in your full HTML & CSS
If you are on Chrome, try lowering the zoom. I played around some eventually setting mine at 80% and it worked.
Thank you designrockstar2279! I tried this & it worked! I am going to post this over in the other place I saw comments about this for other people, so they can hopefully progress too! You saved me mucho time-o! Really appreciate it! Don't think I would have figured it out- and seems like others are stuck too! Good job..
