+<p>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.</p>
+<p>This rule ignores <code>$sass</code>, <code>@less</code>, and <code>var(--custom-property)</code> variable syntaxes.</p>
+<h2>Noncompliant Code Example</h2>
+<pre>
