In my opinion specifying "0.5" is simply wrong. The property expects, 
among others, a <percentage> or a <length>. So one should specify either 
"50%" or "0.5px", but not a number alone since it becomes impossible to 
determine if it’s a percentage or a length. An error should probably be 
thrown in this case.
