title: JavaScript button link on one page to show hidden div on another page
body: <p>I have a home.html and faq.html.</p>
  
  <ol>
  <li><p>The faq page has many questions and their answers listed consecutively down the page. I want the answers hidden until a question is clicked that opens that answer. When another question is clicked, it will close the previous answer and open the new one. I'd like to use <code>slideUp</code>/<code>slideDown</code> or <code>fadeIn</code>/<code>fadeOut</code> for that, but not essential.</p></li>
  <li><p>The home page has a link that when clicked, I want taken to the faq page and also have 'open' a specific answer, both from the one click; <code>slideDown</code> or <code>fadeIn</code> again not essential.</p></li>
  </ol>
  
  <p>Is there a JavaScript that can be used to perform the task?
  I have seen some posts with <code>setvisibility</code> type code somewhat acceptable for the faq page, but not that I can activate from my home page.
  I am a novice, so I ask for the html code too that I can insert on both pages. A bigger chore than usual I know!
  Many thanks.</p>
  
  <p>NOTE
  I now see a problem with my idea because of the following. I didn't mention it before but it would be neccessary.
  Let me try to explain it.
  I now find that to have a link on one page open another page at a particular position down that page will
  correctly position the page to that point IF previous content on that page is not hidden.
  If previous content is <code>visibility: hidden;</code>, that point where the page will open at is innacurate. In other words, it opens at a point below intended, a point at which is correct if previous content is not hidden.
  I hope that makes some sense.
  I will soon look at whether <code>display:none;</code> is better suited for this before I look at my original questions.
  Thanks to those who have helped me to date, you have spent a lot of time for me.</p>
