Deprecated HTML Tags

What does "deprecated" mean?

Generally, "deprecated" means something disapproved. In IT, deprecated elements are the ones that are allowed, but not recommended and are being replaced by newer ones. So, if you see a "deprecated code", it just means that it is not recommended to use, because there is a better alternative in that software that should be used instead.
