Page: http://www.w3schools.com/css/tryit.asp?filename=trycss_image_transparency Includes a tip that IE requires a doctype tag -- but the tip doesn't display correctly. There may be a more elegant solution, but this one works (less the spaces added so the tags will show up): < c o d e > < < / c o d e > ! D O C T Y P E >

The page http://www.w3schools.com/html/html_videos.asp incorrectly describes the technique being recommended. The page has "The example below uses the <video> element and tries to play the video either as MP4 or OGG. If that fails, the code "falls back" to try the <embed> element:" But the code that follows the statement takes a 3-step approach. The description should be: The example below uses the <video> element and tries to play the video either as MP4 or OGG. If that fails, the code "falls back" to try the <object> element to play the video as MP4. And if that fails, the code "falls back" to try the <embed> element to play the video as SWF: There is a similar error in the corresponding page about playing audio.
