Html 5 in a big nutshell

HTML 5 is a new version of HTML that is still being developed. It aims to evolve HTML instead of reinventing it. Key features include new form elements, input types, semantic elements, APIs for offline apps, and standardized video and audio embedding. Browser support is growing but the specification may not be finalized until 2022. However, many features are already implemented and can be used today through emulation if needed.
