C-HTML（cHTML或Compact HTML）是HTML的子集，用于i-mode手提电话。它支持一些标准HTML没有的功能如快捷键、电话号码连接和绘文本，这些概念都来自HDML／WML。它由ACCESS和主要的日本手提电话制造商在1998年开发，是WML和XHTML Basic的竞争者。C-HTML和标准HTML兼容，可以用一般网页浏览器查看。

C-HTML没有WML中的「card」标签。

将来，XHTML Basic很可能取代C-HTML，因为日本的EZ无线数据服务和WAP操作器都支持XHTML。

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 and WML.
