I'd like to extend my thanks to a few people who directly or indirectly helped in getting this book written.

Firstly, Matthew Mitchell (http://mattmitchell.co.uk), who provided the http://ecss.io website design, and endures (pun intended) my constant blathering about CSS.

I'd also like to thank my work colleagues at bet365, principally Pete Griffiths (http://twitter.com/kungfusheep) who encouraged the development teams to make use of the ECSS approach on a grand scale.

Finally, I'd like to thank my long-suffering wife for allowing me to 'tap away' in the kitchen for countless hours in order to get this stuff out of my head.
