This is the simplest I can make with pure Xara.

Just add text blocks to the MouseOver layer and activate with linked text on MouseOff, using a Link of "javascript:" (The colon is needed).

  • Paragraph border when added FAILS to display.
  • If links and text blocks of another link overlap you
  • Repel Text Under may through things out.
  • Do use Anchor to text as well as adding new text or moving repel objects will throws things out of alignment.
