Challenge: Learn HTML Forms by Building a Registration Form - Step 55

Link to the challenge:

Hello! Take a look at the previous selector you have, right after the “middle” property value.

This is a huge common mistake we all make all the time. I am going to help you due to you not seeing it, which isnt your fault. In code on the lessons, and I am assuming also in real life work is this. You have to follow correct spacing of your css. Your opening bracket for the elements of width or not spaced next to the main submit element.
