• Using DOM and JavaScript.

A broader UA definition includes Web crawlers, Web bots and other technologies. The browser issues certain UA strings that show the specific technology used to access a site, page or other content. For example, a UA string from a Firefox browser would include the word Mozilla, as well as version data and other details. User agents include browsers, browser extensions, media players, readers and other applications that render web content. A user agent that follows UAAG 2.0 will improve accessibility through its own user interface and its ability to communicate with other technologies, including assistive technologies.
