Eventually, the specification will stabilize even more, and all browsers will implement
the CSS specification the same, and no vendor prefix will need to appear in your
stylesheet code. But until then, you'll need to repeat some CSS Level 3 rules so that
each browser will recognize the feature.
CSS preprocessors
It can sometimes be difficult to keep up with all the CSS features and their corres-
ponding browser support. Some features have already gone out of the prefix (mean-
ing that all major browsers support the rule without the vendor prefix keyword in front
of the rule keyword). Still, many others haven't completely outgrown this experiment-
al stage, and only some of the major browsers support them without any vendor pre-
fix.
Some brave developers make the effort to stay on top of the latest browser updates,
and update their code accordingly, by removing superfluous vendor prefixes from
their stylesheet code. Others find this proactive effort to be counter productive, and
instead include all possible versions of the rule to their code, in which case they
would only need to update their stylesheet code one day in the far future, if at all.
