sorry my final question was altered by a filter.
“also, i see references to something like  [DASH] [DASH] smart [DASH] editor [DASH] height  — are we supposed to be setting the css values prefixed by the double dashes?”
its interesting to note that the following line is required as the first line in order to get htmlelements to work:
<   !  DOCTYPE  html >   (spaces intentionally added to override possible filtering)
some legacy webpages might not include this as the first line.
