  • When zooming in on text content, the text readjusts (reflows) to fit the screen so a user does not need to pan the screen to read the larger text


  • Reflow on Zoom initiated only when a user double taps (and not when a user pinches)
  • Reflow to feel smooth and not abrupt
  • Reflow should centre around the 'double tap' in order to zoom in on the intended content
  • Zooming in on images should not trigger a reflow
    • (jwir3): I thought we wanted to reflow regardless of what the user clicks on. The rationale for this is if the user zooms into an image/preformatted text/etc..., we want them to be able to read the text surrounding the image when they pan without zooming out and zooming back in.

User stories

  • As a user, when I double-tap on text on a part of a page, the page zooms in at a comfortable level and the text and images reflows naturally around this zoomed-in area without the need to scroll horizontally, so I can easily and fluidly read and hone in on areas of the page that I am reading.
