====== 6.5. Do not refer to an item by indicating its colour, shape, or position alone ======

If you only refer to the colour, shape or position of an element to identify it, then some users will be unable to locate it on the page.

For example, you should replace:
  * “Click the round button” by “Click the send button”.
  * “For more information see the insert on the right” by “For more information see the insert on the right (Wiltshire contract)”.
