Firefox OS apps should always specify a viewport <meta> tag

Published: | Categories: DOM


Firefox OS 1.3, based on Firefox 28, added the support for a viewport <meta> tag in applications. The default viewport "width=device-width, height=device-height, user-scalable=no" will be applied to apps that don’t specify one. This implementation is only for backward compatibility and will eventually be removed. Open Web App developers are encouraged to always declare a viewport <meta> tag to avoid a possible breakage in the future.
