The document discusses new features in HTML5 including semantic elements, form elements, and microdata. Some key points: 1. HTML5 introduces new semantic elements like <header>, <footer>, <nav>, <article>, and <section> to define different parts of a page and improve semantics and accessibility. 2. New form input types are added like email, url, tel, number, date to support validation and new UI widgets. Attributes like placeholder, autofocus, and autocomplete improve the form experience. 3. Microdata builds on microformats to embed structured data using attributes like itemscope, itemtype, and itemprop to identify items, properties and values for search engines and APIs
