Hi Aylan Calletti,

It is not the issue on closing the curly braces. The braces are closed in the right way. the Curley braces that you mentioned is for the couple of blocks for media queries.
The actual issue is, there is a comma sign (,) on line no 77. Its the wrong syntax. For the group selector, there should not be comma sign (,) on the end selector.

Thanks
