People have their own preference about the location of closing brackets. This rule enforces a line break (or no line break) before tag's closing brackets.

<div
  id="foo"
  class="bar"> <!-- On the same line with the last attribute. -->
</div>

<div
  id="foo"
  class="bar"
> <!-- On the next line. -->
</div>
