[det]html_post(+Id, :HTML)//

Reposition HTML to the receiving Id. The html_post//2 call processes HTML using html//1. Embedded \-commands are executed by mailman/1 from print_html/1 or html_print_length/2. These commands are called in the calling context of the html_post//2 call.

A typical usage scenario is to get required CSS links in the document head in a reusable fashion. First, we define css//1 as:

css(URL) -->
        html_post(css,
                  link([ type('text/css'),
                         rel('stylesheet'),
                         href(URL)
                       ])).

Next we insert the unique CSS links, in the pagehead using the following call to reply_html_page/2:

        reply_html_page([ title(...),
                          \html_receive(css)
                        ],
                        ...)
