I have developed a simple, content-management-system-agnostic PHP-HTML-JavaScript-CSS contact form which I normally embed by iframe but I no longer want to use iframe due to the form appearing partially in mobile display with scrolling needed to view all of it.
I can use this CSS as a partial solution:
@media screen and (max-width:733px) { #prcf_iframe { height:547px; } }
This is neither a "pixel perfect" solution nor anything near pixel perfect because in some mobile displays the form either still has some scrolling area or, in other mobile displays, suddenly has some extra "dead height area".
How could I show this CMS-agnostic form in Drupal without using iframe?
Due to the form being CMS-agnostic by design, it should also not be part of a Drupal module.
