title: How to embed other websites via iframe / ahref?
body: <p>I have html site - i would like to do the following </p>
  
  <pre><code>-----------------------------
  Link1 website1     | 
  Link2 website2     | Mysite
  Link3 website3     |
  -----------------------------
  </code></pre>
  
  <p>As you can see, on right side, content will be 
  static - Its from my website.</p>
  
  <p>On left side there is 3 links (a href) - which point to
  three different domain. </p>
  
  <p>Now how to ensure, when I click on link1, website1 content displayed</p>
  
  <pre><code>---------------------------------
              | 
  Website1    | Mysite
              |
  ---------------------------------
  </code></pre>
  
  <p>If link2 clicked, Website2 content will be displayed. </p>
  
  <p>bonus question : Embedding other site like this way , cause any security
  threat to my site?</p>
  
  <p>google gave me this : </p>
