Mozilla Html



HTML5 is the latest evolution of the standard that defines HTML. The term represents two different concepts. It is a new version of the language HTML, with new elements, attributes, and behaviors, and a larger set of technologies that allows the building of more diverse and powerful Web sites and applications. This set is sometimes called HTML5 & friends and often shortened to just HTML5.

Html

Designed to be usable by all Open Web developers, this reference page links to numerous resources about HTML5 technologies, classified into several groups based on their function.

Html
  • Semantics: allowing you to describe more precisely what your content is.
  • Connectivity: allowing you to communicate with the server in new and innovative ways.
  • Offline and storage: allowing webpages to store data on the client-side locally and operate offline more efficiently.
  • Multimedia: making video and audio first-class citizens in the Open Web.
  • 2D/3D graphics and effects: allowing a much more diverse range of presentation options.
  • Performance and integration: providing greater speed optimization and better usage of computer hardware.
  • Device access: allowing for the usage of various input and output devices.
  • Styling: letting authors write more sophisticated themes.

User CSS (changing fonts, colors and other style) Much of Mozilla's fonts and colors are controlled via CSS (Cascading Style Sheets). These are set in.css files in Mozilla's chrome directories, but the user can override them with two plain text files, called userContent.css and userChrome.css. An HTML element is set off from other text in a document by 'tags', which consist of the element name surrounded by ' '. The name of an element inside a tag is case insensitive. That is, it can be written in uppercase, lowercase, or a mixture. For example, the tag can be written as, or in any other way.

Semantics

Sections and outlines in HTML5
A look at the new outlining and sectioning elements in HTML5: <section>, <article>, <nav>, <header>, <footer> and <aside>.
Using HTML5 audio and video
The <audio> and <video> elements embed and allow the manipulation of new multimedia content.
Forms improvements
A look at the constraint validation API, several new attributes, new values for the <input> attribute type and the new <output> element.
New semantic elements
Beside sections, media and forms elements, there are numerous new elements, like <mark>, <figure>, <figcaption>, <data>, <time>, <output>, <progress>, or <meter> and <main>, increasing the number of valid HTML5 elements.
Improvement in <iframe>
Using the sandbox and srcdoc attributes, authors can now be precise about the level of security and the wished rendering of an <iframe> element.
MathML
Allows directly embedding mathematical formulas.
Introduction to HTML5
This article introduces how to indicate to the browser that you are using HTML5 in your web design or web application.
HTML5 Reference Guide
Quick-reference HTML5 sheet containing markup generators, code examples and web developer tools. The guide is downloadable for ease of use and access. This page was created with help from the W3C as a quick guide for those who have some basic familiarity and experience using HTML5.
Downloadable HTML5 Guide
A quick guide to HTML5, including the common HTML tags as well as the new HTML5 tags. Downloadable in PDF and PNG formats.
HTML5 Cheat Sheet
A handy HTML 5 cheat sheet for beginners who want to master HTML 5, its elements, event attributes and compatibility.
Editable HTML5 Cheat Sheet
A beginner-friendly and editable cheat sheet with HTML5 examples that is aimed at anyone wanting to learn and use HTML5.
HTML5-compliant parser
The parser, which turns the bytes of an HTML document into a DOM, has been extended and now precisely defines the behavior to use in all cases, even when faced with invalid HTML. This leads to far greater predictability and interoperability between HTML5-compliant browsers.

Connectivity

Web Sockets
Allows creating a permanent connection between the page and the server and to exchange non-HTML data through that means.
Server-sent events
Allows a server to push events to a client, rather than the classical paradigm where the server could send data only in response to a client's request.
WebRTC
This technology, where RTC stands for Real-Time Communication, allows connecting to other people and controlling videoconferencing directly in the browser, without the need for a plugin or an external application.

Offline & storage

Offline resources: The application cache
Firefox fully supports the HTML5 offline resource specification. Most others have offline resource support at some level.
Online and offline events
Firefox 3 supports WHATWG online and offline events, which let applications and extensions detect whether or not there's an active Internet connection, as well as to detect when the connection goes up and down.
WHATWG client-side session and persistent storage (aka DOM storage)
Client-side session and persistent storage allows web applications to store structured data on the client side.
IndexedDB
IndexedDB is a web standard for the storage of significant amounts of structured data in the browser and for high performance searches on this data using indexes.
Using files from web applications
Support for the new HTML5 File API has been added to Gecko, making it possible for web applications to access local files selected by the user. This includes support for selecting multiple files using the <input> of typefile HTML element's new multiple attribute. There also is FileReader.

Multimedia

Using HTML5 audio and video
The <audio> and <video> elements embed and allow the manipulation of new multimedia content.
WebRTC
This technology, where RTC stands for Real-Time Communication, allows connecting to other people and controlling videoconferencing directly in the browser, without the need for a plugin or an external application.
Track and WebVTT
The <track> element allows subtitles and chapters. WebVTT is a text track format.

2D/3D graphics AND effects

Canvas tutorial

HTML5 Text API for <canvas> elements
The HTML5 text API is now supported by <canvas> elements.
WebGL
WebGL brings 3D graphics to the Web by introducing an API that closely conforms to OpenGL ES 2.0 that can be used in HTML5 <canvas> elements.
SVG
An XML-based format of vectorial images that can directly be embedded in the HTML.

Performance and Integration

Web Workers
Allows delegation of JavaScript evaluation to background threads, allowing these activities to prevent slowing down interactive events.
XMLHttpRequest level 2
Allows fetching asynchronously some parts of the page, allowing it to display dynamic content, varying according to the time and user actions. This is the technology behind Ajax.
JIT-compiling JavaScript engines
The new generation of JavaScript engines is much more powerful, leading to greater performance.
History API
Allows the manipulation of the browser history. This is especially useful for pages loading interactively new information.
The contentEditable Attribute: Transform your website to a wiki!
HTML5 has standardized the contentEditable attribute. Learn more about this feature.
Drag and drop
The HTML5 drag and drop API allows support for dragging and dropping items within and between web sites. This also provides a simpler API for use by extensions and Mozilla-based applications.
Focus management in HTML
The new HTML5 activeElement and hasFocus attributes are supported.
Web-based protocol handlers
You can now register web applications as protocol handlers using the navigator.registerProtocolHandler() method.
requestAnimationFrame
Allows control of animations rendering to obtain optimal performance.
Fullscreen API
Controls the usage of the whole screen for a Web page or application, without the browser UI displayed.
Pointer Lock API
Allows locking the pointer to the content, so games and similar applications don't lose focus when the pointer reaches the window limit.
Online and offline 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.

Device access

Using the Camera API
Allows using, manipulating, and storing an image from the computer's camera.
Touch events
Handlers to react to events created by a user pressing touch screens.
Using geolocation
Let browsers locate the position of the user using geolocation.
Detecting device orientation
Get the information when the device on which the browser runs changes orientation. This can be used as an input device (e.g., to make games that react to the position of the device) or to adapt the layout of a page to the orientation of the screen (portrait or landscape).
Pointer Lock API
Allows locking the pointer to the content, so games and similar application don't lose focus when the pointer reaches the window limit.

Styling

Mozilla Html Grid

CSS has been extended to be able to style elements in a much more complex way. This is often referred as CSS3, though CSS is not a monolithic specification any more and the different modules are not all at level 3: some are at level 1 and others at level 4, with all the intermediate levels covered.

New background styling features
It is now possible to put shadows on elements using box-shadow, multiple backgrounds, and CSS filters. You can learn more about these by reading Advanced box effects.
More fancy borders
Not only it is now possible to use images to style borders, using border-image and its associated longhand properties, but rounded borders are supported via the border-radius property.
Animating your style
Using CSS Transitions to animate between different states or using CSS Animations to animate parts of the page without a triggering event, you can now control mobile elements on your page.
Typography improvement
Authors have better control to reach better typography. They can control text-overflow and hyphenation, but also can add a shadow to it or control more precisely its decorations. Custom typefaces can be downloaded and applied thanks to the new @font-face at-rule.
New presentational layouts
In order to improve the flexibility of designs, two new layouts have been added: the CSS multi-column layouts and CSS flexible box layout.

Mozilla Composer is the free and open-sourceHTML editor and web authoring module of the Mozilla Application Suite (the predecessor to SeaMonkey). It is used to create and to edit web pages, e-mail, and text documents easily. It is compatible with Windows, macOS and Linux. Composer is a graphicalWYSIWYGHTML editor. One also can view, write and edit HTML source code with Composer.[1]

Mozilla Html Styles

Linspire sponsored development of Nvu, a stand-alone version of Mozilla Composer which incorporates Cascading Style Sheets support and other improvements from software company Disruptive Innovations.

Daniel Glazman, the lead developer of Nvu, announced on September 15, 2006 that he had stopped official development on Nvu and that he was developing a successor as a Mozilla.org project. It is written from scratch and based on Mozilla trunk Gecko 1.9 and XULRunner. PHP and CSS would be supported. A community-driven fork, KompoZer, maintains Nvu codebase and fixes bugs until a successor to Nvu is released. Glazman's project is called BlueGriffon.

SeaMonkey, the community-driven successor to Mozilla Suite, includes an HTML editor named Composer that is developed from the Mozilla Composer code contained in the original Mozilla Suite.[1]
