(pronounced as separate letters) Short for compact HTML, a subset of HTML for small information devices, such as smart phones and PDAs. cHTML is essentially a pared down version of regular HTML over the Internet.

Because of the limitations of small information devices, cHTML does not support JPEG images, tables, image maps, multiple fonts and styles of fonts, background colors and images, frames, style sheets and more than two colors, typically black and white.
cHTML is defined so that all the basic operations can be done by a combination of four buttons and not by two-dimensional cursor movement: cursor forward, cursor backward, select, and back/stop. The functions that require two-dimensional cursor pointing, like “image map” and “table,” are excluded from cHTML.
cHTML was created by Japan-based Access Company, Ltd. for use in i-mode devices, and was accepted by the W3CM in 1998. cHTML has been fading into obsolescence as XHTML gains acceptance and replaces cHTML.
