title: Are self-closing input tags valid in HTML 4?
body: <p>According to <a href="http://www.w3.org/TR/html401/interact/forms.html#h-17.4" rel="noreferrer">http://www.w3.org/TR/html401/interact/forms.html#h-17.4</a>, an input element should end with a single <code>&gt;</code> and not a <code>/&gt;</code>. Though that most browsers can handle an input element that ends with <code>/&gt;</code>, is such an input element valid according to HTML syntax rules? In other words are elements like <code>&lt;input ... /&gt;</code> and <code>&lt;br /&gt;</code> valid in <strong>HTML</strong> 4?</p>
  
  <p>(This question is about HTML and not XHTML!!!)</p>
