Is CSS giving error?

Question

At a recent interview I was asked the question \"Is CSS giving error?\" by the interviewer.

Is there an interpreter working behind CSS which blocks

Answer 1

Some browsers will report CSS errors in the console. Firefox comes to mind.

results in the error:

Unknown property 'bar'. Declaration dropped. css-error.html:2:11

However, this will not "block execution of the program".

To my knowledge, no similar feature exists in Chrome.
