Vertical issues with YouTube modal window, CSS and HTML only -


i'm trying make modal window plays youtube video. final result should dynamically resize fill contents of viewport while respecting 16:9 aspect ratio. should stop expanding once has reached 720p.

i'm running these problems:

  1. the video not respect height of viewport if width large (overflow)
  2. the video not @ vertically centered

i have no idea @ how fix these. have looked hours @ many similar stack overflow questions , have not made progress. there hope?

my html:

<div id="youtube-overlay">     <div id="youtube-margin">         <div id="youtube-container">             <iframe class="youtube-hd" src="http://www.youtube.com/embed/novw62mwsqq?rel=0&autoplay=1&autohide=1&showinfo=0" frameborder="0" ></iframe>         </div>     </div> </div>

my css:

#youtube-overlay {     background-color: rgba(0, 0, 0, .85);     height: 100%;     width: 100%;     left: 0;     top: 0;     position: fixed;     z-index: 999999;     visibility: hidden; }  #youtube-container {     position: relative;     max-width: 1280px;     max-height: 100%;     margin: 0 auto;     padding-bottom: 56.25%; }  #youtube-margin {     margin: 10px; }  .youtube-hd {     position: absolute;     max-height: 720px;     height: 100%;     width: 100%; }

try this:

<head> <style type="text/css"> .youtube-hd { width:100%; height:100%; max-height:720px; max-width:1280px; } </style> </head> <body> <table style="width: 100%; height:100%;"> <tr>  <td style="text-align: center; vertical-align: middle;">       <iframe class="youtube-hd" src="http://www.youtube.com/embed/novw62mwsqq?rel=0&autoplay=1&autohide=1&showinfo=0" frameborder="0" ></iframe>  </td> </tr> </table> </body>

you don't need divstructure had.
