Typography (cont)

Design/Content

The web is not the constitution (media queries)

http://responsive.ishttp://mediaqueri.es/

Design/Content

What about my media? HTML5 audio/video and fallbacks

jPlayer Video/Audio:http://jplayer.org/

VideoJS:http://videojs.com/

Design/Content

What about my media? Multi-res images and fallbacks

Content:- Save your images larger- Some CSS:

img, embed, object, video{ max-width: 100%;}

about img { width: 30%;}

Won’t work in IE6, but there are work-arounds out there!

Image Transparency/Max-width Fixes:http://msdn.microsoft.com/en-us/library/ms532969(v=vs.85).aspx

Handy Media Queries for Backgrounds:.your-image { background:url(picture.png); width: 20px; height: 20px;}

@mediaonly screen and (-webkit-min-device-pixel-ratio: 1.5),only screen and (min-device-pixel-ration: 1.5) { .your-image { background-image: url(picture@2x.png); -webkit-background-size: 20px 20px; background-size: 20px 20px; }}

File-size Considerations:Picture Fill: http://scottjehl.com/picturefill/<picture alt=“blah”> <source src=“something.jpg” /> <source src=“something-big.jpg” media=“(min-width:800px)” /> <noscript><img src=“something.jpg” alt=“blah” /></noscript></picture>

3. Find Heroku URL from your account4. Read and do Hello World Phone Gap app, and use that URL instead of the

default file:/// url they specified5. Your first mobile app using nodejs and express on heroku with phonegap is done
