From the Feedbooks blog:
For the last two months, we’ve been rolling out new features at an hectic pace: among the major ones, we fully redesigned our mobile website:
touch friendly buttons for iOS and Android users
CSS3 effects for a smoother experience
fully localized in English and French
new subdomains: m.feedbooks.com and m.fr.feedbooks.com
fully featured, with the ability to browse facets like on the full website
designed for speed (according to Google, we’re now faster than 75% of the Web on our main domain, and faster than 90% on our French subdomain)The most challenging part, was to design a system that would enable the same facet-based navigation than on our full website.
