All this week we're offering 20% off a selected Practical Guide title each day. Today's title is A Practical Guide to Designing the Invisible by Robert Mills. Designing for the web is not just about fancy layouts, the latest CSS3 or HTML5 or UX technique. Great web experiences tell a great story, and this book will give you the tools to help you do it.

Since its launch in July 2011, Designing the Invisible has been endorsed by the likes of Elliot Jay Stocks and Laura Kalbag. Simon Collison said of it:

“I continue to recommend Designing The Invisible to anyone who’ll listen. This book is beautifully organised, and Robert’s style is warm and open. Using familiar examples and thoughtful case studies, he lifts the lid on how subtle and invisible design can help improve our dialogue with audiences, and help them make sense of complexity.”

As well as writing and editing for well-known publications such as Smashing Magazine and The Insites Book, Rob has also ventured into the world of speaking - most recently at Handheld Conference.

An essential book for any designer's shelf, you can pick up a copy - paperback or digital edition - with 20% off, all day today. Treat yourself!
