**Link to the challenge:**

you have missed the space in media query - @media only screen and(max-width:550px)

it still didn’t work .

As @Rockky1997 said, there needs to be a space between and and (max-width:550px) . If the tests don’t pass for you even if you do that check if you have any extensions on your browser which might be messing with the tests. If the problem continues, you could either reset the test or try to attempt this challenge on some other browser.
