Hello!
Please post your complete code? The issue sometimes is not with the posted code but in another area of the code.
You can use the Help
image

which appears on every step of the Responsive Web Design after three unsuccessful attempts at the step.

You could also try resetting the step and reentering it to see if it goes through.
Or using a different browser may help.
