Intent of Success Criterion 1.8.6:
Some users want to be able to magnify content to make it more legible. Some users  want to be able to shrink content so that more of the content is visible onscreen, which can help them understand the structure of the content and their position in  the content, even if text has become too small to read.

Examples of Success Criterion 1.8.6:
- A web application uses small text fonts, mixed with graphical elements. The user tries increasing the text size alone, but the graphical elements remain at their original sizes, causing the application to be displayed improperly. Instead, the user zooms in on the application, which makes the text more legible without breaking other aspects of the presentation. 
- A viewport is used to display an image depicting an organization chart. A user with a learning disability has difficulty maintaining a mental representation of the organizational linkages for items out of view. In order to facilitate their understanding of the organization, the user zooms out to allow the entire chart to be displayed.
