Working within a team or solo can adjust the development priorities but one that should always be high on the agenda is producing the best code possible.
Working on a clean, well organised codebase is bliss. It’s enjoyable and productive. Working on an unorganised codebase is annoying to say the least. It’s often frustrating, painfully slow to change and test anything and invites laziness.
Thankfully as CSS developers we have a handy tool called Stylelint that can help us avoid the unorganised situation.
