IsCHTMLBrowser<\/h2>\n

This function checks whether a given user agent value is a C-HTML browser.<\/p>\n

C-HTML, or Compact HTML, is a subset of the HTML markup language that was developed for small information devices, such as first-generation smart phones and PDAs. The language does not support tables, image maps, multiple fonts or styling of fonts, background colors or images, frames, or style sheets, and is limited to a monochromatic display. This standard was superseded in early 2000 by other markup languages, due to advancements in mobile technology.<\/p>\n

This function is only available in landing pages, microsites and CloudPages. It cannot be used in other Marketing Cloud applications.<\/p>\n
