title: Can I modify the HTML <input type="time"> element to step by 15 minutes?
body: <p>Normally, when you click on a HTML  input element, it allows you to select any hour and minute (6:01, 6:02, etc.). But I want to add a time input element that only allows you to select times along 15-minute intervals (6:00, 6:15, 6:30, etc.) to the page I'm working on.</p>
  <p>The documentation says that you can use the &quot;step&quot; attribute on the  element to tell it the number of seconds between each of the selectable time increments. 15 minutes is 900 seconds, so I tried:</p>
  <pre><code>&lt;input type=&quot;time&quot; step=&quot;900&quot;&gt;
  </code></pre>
  <p>but that appeared to be no different from when the &quot;step&quot; attribute was not used.</p>
