Pattern: Disallow !important
Issue: Use of !important
The !important annotation is used to artificially increase the specificity of a given property value in a rule. This is usually an indication that the specificity of the entire CSS has gotten a bit out of control and needs to be refactored. The more frequently !important is found in CSS, the more likely it is that developers are having trouble styling parts of a page effectively.
Rule ID: important
This rule is aimed at keeping your specificity levels in check. As such, it warns whenever !important is used.
