Hey there,

the problem in your code is that you have a space between the properties and the following colons. You have to write the colons immediately after the property. Also note that the space between the value and the ";" is not necessary either.

And about what Jim mentioned: Yes, the challenge doesn't ask that but if you're setting the margin to auto you're setting the margin on every side to auto. The margin-top and margin-bottom values compute to zero in this case so that's not the problem why this challenge isn't passing as the result is the same.

This should do it:

/* Complete the challenge by writing CSS below */
.container{
  width: 80%;
  margin: 0 auto; 
}

I hope that helps! :)

The challenge doesn't ask you to set top and bottom margin so you should use:

margin: auto;

good luck
