Getting Started

Pixel Perfect is a firefox firebug extension that allows web developers to easily overlay a web composition over top of the developed html. Switching the composition on and off allows the developer to see how many pixels they are off while in development.

To get started, click on the "Add overlay" button to add your design composition.

For more information, please refer to the "Help" menu, or visit http://www.pixelperfectplugin.com
