Download Jeremy Keith's HTML5 For Web Designers book source code for offline study. Apart from the great content, its markup is a great simple and easy to read example of:
- offline caching
- responsive Web design
- micro formats
- CSS3
- custom fonts
- more every time I dig through it
The download.sh script just parses the manifest file and downloads all of the content is a folder named html along the script.
Have fun exploring Jeremy's source code!
