Hello,
So far its just cleaning up the code using best practices. Usually means more work for programmers and designers if they haven't been keeping up with it. A lot of programmers like to write their code a certain way usually because they have been doing it for a while. If they get no errors from validators or if everything works, they see no reason to change how they write it!
For example, I use the
tag for a line break, where the styleguide recommends
. Both achieve the same result however, I feel comfortable knowing my tags are closed />.
Same with the tag. I've gotten used to using it. So not using feels odd and like somethings missing.
