I love how "good" parts fail. Don't use "click here" [1] <audio> <source /> <p><a>Birds singing in the morging</a></p> </audio> How would retina display render <video>? <video controls> <source src="video-small.mp4" type="video/mp4" media="all and (max-width:480px)"> <source src="video-small.webm" type="video/webm" media="all and (max-width:480px)"> <source src="video.mp4" type="video/mp4"> <source src="video.webm" type="video/webm"> </video> And you probably should use min-device-pixel-ratio [2], oh, it is deprecated [3], time to use resolution [4]. Should search index <audio> fallback? Google does [5]. Did you know it does not index <script> and <style> content?
