title: HTML & CSS - Create warning message for users with too low a resolution?
body: <p>My website currently has a width too high to be viewed at 800x600 resolution or lower. What I would like to do is to create some kind of warning message, so when someone with a resolution this low they are made aware that the site will not view properly. Preferably, I would like a yellow bar to drop down from the top much like Internet Explorer does.</p>
  
  <p>How can I do this by using HTML and CSS? If you can't, please tell me how to do it in any other language.</p>
  
  <p>Thanks</p>
