Agree completely with Bryan and others    Instead  consider using multiple sections in your email that you can jump to using links and anchors  the  a  tag   I think that you can emulate the behavior you want by including multiple copies of the text further down in your email  This is a bet messy though  so you could just have sets of anchors that link to each other and allow you to move back in forth between the  summary  section and the  expanded  one    Example    lt a href   section1  gt Jump to section  lt  a gt   lt p gt A bunch of content lt  p gt   lt h2 id  section1  gt An anchor  lt  h2 gt    Clicking on the first link will move focus to the sub-section
