CSS allows duplicate property names but only the last instance of a duplicated name determines the actual value that will be used for it.
Therefore, changing values of other occurrences of a duplicated name will have no effect and may cause misunderstandings and bugs.
This rule ignores $sass, @less, and var(--custom-property) variable syntaxes.
Noncompliant code example
