title: "Don't use IDs in selectors (CSS)" then, what to use instead of IDs?
body: <p>One of <a href="https://github.com/CSSLint/csslint/wiki/rules" rel="noreferrer">CSS lint rules</a> is: &quot;It's better to not use IDs in selectors&quot;.
  So, what should we use instead of IDs to point to a unique element?
  For example, say I have dozens of elements that have a class named <code>my-class</code>, and I want only one of them to have a special CSS property. What can I do?</p>
