Volantis has expanded its core mobile content delivery platform with the launch of Framework 6.0, which the company says allows developers to build superior websites and applications using HTML5 and CSS3.

A new app creator, an enriched HTML5 and CSS3 toolkit, and better device portability and improved page rendering are the key features included in the new release, the company said.

The new app creator allows developers to deploy applications that can run across native and web clients and be packaged up for both Apple and Android app stores.

The toolkit allows HTML5 developers to produce a compelling user experience, allowing all applications and websites to utilise, gradient, 3D transforms, cover flow, reflections and opacity amongst other properties.

In addition, the new release also addresses some of the portability challenges which developers face as a result of the differences in new HTML5 browser standards.

Mark Watson, CEO of Volantis, said: "HTML5 offers great potential for developers to produce web-based applications which offer a rich media experience.

"However, as browser vendors implement different features for HTML5, end-users might not be able to take full advantage of their device’s capabilities.

Mr Watson added: "For developers, this usually means designing applications that have to be tweaked to overcome the bugs unique to each manufacturer’s version of HTML5 and CSS3 employed.

"With Framework 6.0, developers can produce browser-based and native applications with highly customisable, out-of-the-box user interface components, which fulfill the potential of the latest handsets as well as rendering across legacy devices."
