Docs For Class TranscodingActionCSSAdaptation

Description

Transcoding action that adapts CSS content to improve content layout on mobile devices.

The DDR property reference that the transcoding action uses to tell whether the requesting device is mobile or not may be defined as a "mobile_device" option through a call to TranscodingAction::setOption(). The action uses the is_wireless_device property of the WURFL namespace when the option is not set.

As opposed to most of the other transcoding actions of this library, this action operates on CSS content, not on XHTML content.
