title: Is CSS giving error?
body: <p>At a recent interview I was asked the question "<strong>Is CSS giving error?</strong>" by the interviewer. </p>
  
  <p>Is there an interpreter working behind CSS which blocks execution of the program? Or can we say that CSS does not give any error? I am still confused as to what is the answer to this question because the interviewer also did not say anything.</p>
