This page provides links to topics related to HTML Version 5 (HTML5). Some topics are commonly associated with HTML5 but are not actually part of the HTML5 standard. Those topics are linked here for convenience.

HTML

Audio and video

Firefox 3.5 introduced support for the HTML 5 <audio> and <video> elements, offering the ability to easily embed media into HTML documents.

Canvas

<Canvas> is a new HTML element which can be used to draw graphics via scripting (usually JavaScript). For example, it can be used to draw graphs, make photo compositions or even perform animations.
Reference:

WebGL (separate specification)

WebGL brings 3D graphics to the Web by introducing an API that closely conforms to OpenGL ES 2.0 and can be used in HTML5 <canvas> elements.
Reference: WebGL

Inline SVG and MathML

HTML5 parsing liberates MathML and SVG from XML and makes them available in the main file format of the Web.
Reference:

New link relations

Link relations complement the <a> tag and specify why you're pointing to another page.
Reference:

Web forms

Form elements and attributes in HTML5 provide a greater degree of semantic mark-up than HTML4 and remove a great deal of the need for tedious scripting and styling that was required in HTML4.
Reference:

Microformats (separate specification)

Microformats allow web sites to provide semantic data to the browser in order to make it possible to present summaries of the information on a page without having to know how to parse the document itself.
Reference: Using microformats

Semantic tags

The HTML5 specification brings several new elements to web developers allowing them to describe the structure of a web document with a standard semantics.
Reference:

JavaScript (separate specifications)

Client-Side Storage

Firefox supports the HTML 5 specification for offline caching of web applications' resources and offline storage of data.
Reference:

IndexedDB

IndexedDB is an evolving web standard for the storage of significant amounts of structured data in the browser and for high performance searches on this data using indexes.
Reference: IndexedDB

Web workers (separate specification)

Workers provide a simple means for web content to run scripts in background threads.  Once created, a worker can send messages to the spawning task by posting messages to an event handler specified by the creator.

New events

In order to build a good offline-capable web application, you need to know when your application is actually offline. Incidentally, you also need to know when your application has returned to an online status again.

Drag and drop

Firefox and other Mozilla applications support a number of features for handling drag and drop. This allows you the user to click and hold the mouse button down over an element, drag it to another location, and release the mouse button to drop the element there.
Reference: Drag and Drop

Protocol handler

It's fairly common to find web pages link to resources using non-http protocols. You can think of this as a desktop-based protocol handler.

Reference: Web-based protocol handler

Geolocation

The Geolocation API allows the user to provide their location to web applications if they so desire.  For privacy reasons, the user is asked to confirm permission to report location information.
See also: Geolocation Specification

Focus attributes

The focus atributes let a script understand if an element has the focus of the user and then act accordingly.
