HTML5 & CSS3 - A Evolução da Web
The document discusses the evolution of HTML and CSS standards. It covers new semantic elements in HTML5 like <header>, <nav>, <section>, and <article>. HTML5 also introduces new form input types, multimedia elements <video> and <audio>, and the <canvas> element. CSS3 adds new selectors, properties for opacity, backgrounds, borders, shadows, text effects and 3D transforms. The document emphasizes that HTML5 and CSS3 are still works in progress with evolving browser support, and other technologies still have roles to play for applications needing advanced features.
