body: <p>How do I limit or restrict the user to only enter a maximum of five characters in the textbox?</p>
  
  <p>Below is the input field as part of my form:</p>
  
  <pre><code>&lt;input type="text" id="sessionNo" name="sessionNum" /&gt;
  </code></pre>
  
  <p>Is it using something like maxSize or something like that?</p>
