regarding the latest video on gap vs margin at the end there was the spacing between those form-groups would there be a difference (in outcome or styling semantics) if instead of
form { display: grid; gap: 1em;}
form { display: grid; gap: 1em;}
it would have been done
.form-group { margin-block: 1em;}
.form-group { margin-block: 1em;}
because that .form-group selector was already there anyway
