HTML checkers (linters) are also useful. These packages take a look at documents for unique problems, along with a few resulting from invalid markup and others as a result of not unusual browser insects. Checkers may also skip some invalid documents, and they will fail some legitimate ones.

All validators are functionally equal; whilst their reporting styles may vary, they will discover the equal mistakes given equal enter.
