C-HTML (short for Compact HyperText Markup Language), also called i-mode-HTML, is a subset of HTML for small information devices, such as first generation smart phones and PDAs, such as DoCoMo`s i-mode mobile phones used in Japan. C-HTML adds several features not found in standard HTML, notably accesskeys, phone number shortcuts for links, and emoji pictorial characters as locally extended Shift JIS, all concepts borrowed from HDML/WML.
