title: CSS match elements with ANY attribute
body: <p>Is there a CSS selector that matches elements that have ANY attribute?</p>
  
  <p><code>&lt;div&gt;</code>, <code>&lt;p&gt;</code>, and <code>&lt;h2&gt;</code> would not match but <code>&lt;div class="important"&gt;</code>, <code>&lt;p align="left"&gt;</code> and <code>&lt;h2 id="rt0"&gt;</code> would.</p>
