The SciVerse applications platform enables developers to build apps based on trusted scientific content. Learn more. HTML5 is no longer just a buzz word. It — along with JavaScript and CSS3 — is quickly helping reshape perceptions of what a web browser and web standards can achieve. With browsers implementing more HTML5 features across platforms and devices, developers are starting to integrate many of the new features and frameworks into their web apps, websites and web designs.
