Thanks - the placeholder now displays in the correct position. I had just cut and pasted the code the software support people provided. It seems to me that placeholders and display of code and scripts is a bit of a hit and miss process in Xara. In some instances the size of the placeholder container had no bearing on the actual size of the content, other times it is a variable. Adjusting width and length parameters of code creates random results, sometimes it fits and what I preview is what I see in a browser, other times what the browser shows is different. To make it more infuriating, different Iframe code inserted in two identical pages renders differently on a mobile device. Is it a Xara thing or Iframe code in general. Do people using products like WordPress and Jooomla have the same issues?
