HTML5 is the latest generation of markup languages used to create content for the web. It is also used as a programming language for mobile (smartphone and tablet) application development. When people say "HTML5," they typically mean not only the latest version of HTML, but also CSS, JavaScript®, and various markup languages used to represent other kinds of web content, such as SVG (graphics) and MathML (mathematical formulas).

You might reasonably feel that web standards from 10 years ago have nothing to do with authoring web content today. However, many of the web browsers developed to support older standards are still in use today. Understanding how they work will help you develop web content that works for all users, not just those with the latest web browsers.

In the past, a plug-in such as Adobe® Flash® or Microsoft® Silverlight® was typically needed to provide extensive animation and multimedia capabilities within a web browser. With the advent of new mobile devices that do not support such plug-ins, web developers have clamored for an alternative within the native capabilities of web browsers. In response, HTML5 includes support for a wide variety of new animation and multimedia capabilities.

When web authors conceive a design for a website, they often imagine what they would personally like to experience and to build—perhaps something that will show off their skills (a portfolio piece), generate some excitement, and of course, satisfy the client. But when you create a website or HTML5 mobile app, there are many additional consumer needs to think of, such as users special needs due to various types of visual, auditory, motor, or cognitive impairments—as well as machine readers, such as search engine crawlers—programs that systematically access and process websites to create rich databases that help users find your site through search engines such as Google and Bing®.
