Web Standard and Specification Support in QtWebKit

This page documents the supported specifications in QtWebKit. NOTE: this is work in progress and still being reviewed.

Terms used in this documentation

This documentation uses the following classification for the levels of support:

• Not supported: implementation for the feature does not exist or it is so incomplete that even validation and experimentation is not recommended
• Experimental: the implementation of the feature is experimental. The standard or the implementation may still change in future releases, or there may be even significant gaps or limitations in the implementation. Experimentation is required before using the feature in production applications.
• Supported: the feature is fully ready for production applications. We don't expect changes in the API or standard.
