About the Talk

A pixel is not a pixel.

Viewports are pretty easy on desktop: they're the browser window. Thus, an element with width: 10% will span 10% of the browser window, while width: 100px just means a width of 100px.

On mobile, things are quite different. There are two viewports and three kinds of pixels, and they interact in all kinds of weird ways—ways that depend on the browser.

In this technical presentation PPK will explain why a pixel is not a pixel, what the difference between the two viewports is, and which bits web developers should care about.

Caution: Heads may explode!

About the Speaker

Peter-Paul Koch (PPK) is a mobile platform strategist, consultant, and trainer in Amsterdam, the Netherlands. He specializes in HTML, CSS, JavaScript, and browser compatibility.

He has won international renown with his browser compatibility research, frequently speaks at conferences, has founded Fronteers, the Dutch association of front-end professionals, and advises mobile and desktop browser vendors on their implementation of Web standards.

In 2009 he shifted from traditional desktop browsers and sites to the mobile web, and he never looked back. He discovered that mobile devices and browsers are in even more need of description than their desktop counterparts, and set himself to the task. On the Web he is universally known as "ppk."

Currently he has about twenty mobile phones lying around on his desk. The one thing he never does with any of these phones is make a phone call.
