Accessibility Zoom Introduction


In this module, you will not learn about the video service Zoom. You will learn about different ways users use zoom to better see and read the content of a site or app.

Users with low vision zoom in on content to be able to perceive it. Users with good vision zoom in on content to increase the readability of the content. There are three main ways of zooming:

  1. Screen magnifier
  2. Text zoom
  3. Page zoom

You will learn about text and page zoom. As a developer, there is not that much to think about when it comes to screen magnifier.
