rhtm

RHTM (Rich HTML) is an HTML variant that extends the functionality of standard HTML by incorporating additional features. This markup language is designed to provide a more flexible and interactive web page structure. The RHTM specification introduces new tags and attributes that enable developers to create complex and dynamic user interfaces.

RHTM includes the addition of new tags such as `<include>` and `<macro>`, which allow for code reuse and easier maintenance of web applications. The `<include>` tag enables developers to embed external documents or fragments, removing the need for repetition of code in various parts of the website. The `<macro>` tag expands on this concept by providing a way to define and reuse reusable blocks of code, simplifying the development and maintenance process.

Another key aspect of RHTM is the introduction of the `<css>` tag, which allows developers to embed Cascading Style Sheets (CSS) directly within the RHTM document. This streamlines the web design process by eliminating the need to create separate CSS files. RHTM also introduces new attributes for HTML tags, such as the `data-refresh` attribute, which enables developers to add dynamic refresh functionality to web pages.

RHTM is primarily used in web development for creating standalone web applications, as well as desktop and mobile applications. Its ability to combine multiple markup languages and scripting environments into a single document has made it attractive to developers seeking a versatile solution for web development.

While RHTM offers a range of advantages, it remains a niche markup language with limited support from web browsers and development frameworks.
