Essential Components of Web Accessibility
The accessibility of websites relies on the cooperation of eight components:
- the website itself - natural information (text, images and sound) and the markup code that defines its structure and presentation
- user agents, such as web browsers and media players
- assistive technologies, such as screen readers and input devices used in place of the conventional keyboard and mouse
- users' knowledge and experience using the web
- developers
- authoring tools
- evaluation tools
- a defined web accessibility standard, or a policy for your organization (against which to evaluate the accessibility)
These components interact with each other to create an environment that is accessible to people with disabilities.
Web developers usually use authoring tools and evaluation tools to create Web content.
People ("users") use Web browsers, media players, assistive technologies or other "user agents" to get and interact with the content."

Famous quotes containing the words essential, components and/or web:
“I am convinced that, except in a few extraordinary cases, one form or another of an unhappy childhood is essential to the formation of exceptional gifts.”
—Thornton Wilder (1897–1975)
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
“Thou blind man’s mark, thou fool’s self-chosen snare,
Fond Fancy’s scum and dregs of scattered thought,
Band of all evils, cradle of causeless care,
Thou web of will whose end is never wrought;
Desire! desire, I have too dearly bought
With price of mangled mind thy worthless ware;”
—Sir Philip Sidney (1554–1586)
