Does pinch and zoom change the pixels?
When you pinch to zoom in on a photo or a video, what you are actually doing is cropping the viewing size and making it larger. What happens then is things that used to be one pixel large will now take up four or eight or 10 or however many pixels they need in order to make the photo as large as you want it.
What should be avoided to properly support zooming?
Avoid Clipped, Truncated, Obscured, and Overlapping Text
While a page technically fulfills the WCAG criteria if it allows either text resizing or zooming, it is best practice for developers to accommodate both if possible.
What does pinch zoom do?
Pinch to zoom out of content:
After zooming in, touch the video with two fingers, and move your fingers towards one another to zoom out. Once you let go, the video will play at the new zoom level.
How do you keep elements the same size when zooming?
That is, using control-plus to increase text size and control-minus to reduce it.
