Description: GUI for generating custom CARTO popup HTML. Uses CARTO html/css as base, improve style and adds elements. Note because you're working with template injection, you're limmited to HTML and in-line CSS (sorry, no Javascript!). Also, weirdly, you can't seem to add template injection within in-line CSS calc() function.
