Challenge: Step 54

Link to the challenge:

The way you currently have set the margin will set it on all four side. The instructions want you to set it for top and bottom to 1em. You must specify a 2nd value for the left and right.

margin: 1em; <—all four sides
margin: 1em auto;<—first value will be top & bottom…second will be left and right

use rem after value of margin not em or use px

@subhamchaubey510 while I like to use rem myself , the challenge is specifically asking for 1em top and bottom.
