title: How to hide a class using javascript?
body: <p>I have text on a page, its in a <code>&lt;h3&gt;</code> tag, which has a class <code>ms-standardheader</code>, but there are other texts on the page with the same class in its own <code>&lt;h3&gt;</code> tag. I also know the text I want to hide is 'Session'.</p>
  <p>With this how can I write a javascript function to hide only this text?</p>
