title: Is there a CSS selector for elements lacking an attribute?
body: <p>I understand that css rules can target elements specified by attribute values, e.g.:</p>
  
  <pre><code>input[type="text"] {}
  </code></pre>
  
  <p>Can I make a rule that targets elements which <em>omit</em> a certain attribute?  For example, can I target  elements that lack an href or  elements that don't specify a type?</p>
