Goal
- Allow users to adapt the rendering to their needs or preferences, by means of the graphic zoom.
- Improve your positioning in web crawlers that take this criterion into account.
- Improve compatibility with mobile terminals.
Implementation
Do not use any zoom blocking mechanism, and in particular, do not use the minimum-scale, maximum-scale, and user-scalable attributes of the meta viewport element.
Control
Check on a touch screen device that the view can be magnified with the browser's touch zoom control.
