Original code

#elLicenseKey {
	margin: 0;
	border-radius: 0;
  font-size: {fontsize="medium"}};
	padding-right: 40px;
}

rule is closed before padding.

Has to be

#elLicenseKey {
	margin: 0;
	border-radius: 0;
  font-size: {fontsize="medium"};
	padding-right: 40px;
}

 

Thanks, I have fixed this for an upcoming release.
