If you are a web-designer, the bug known as Viewpoint Scaling might have confronted you which occurs in the Apple devices i.e iPod, iPhone and iPad. Sometimes, when we rotate our Apple device from portrait to landscape orientation, the site zooms in, showing us a view having a width larger than the device-width. This is because the designer has set the viewport width to the device width. To help you get an idea how this bug works, we designed a sample page and rotated our iPad from portrait to landscape view.
A quick fix for said bug guides us to set the ‘maximum-scale=1’ in the viewport meta tag. This does fix the problem for the time being but the page is no longer zoom-able because we fix the maximum width similar to the device-width.
<meta name="viewport" content="width=device-width; initial-scale=1; maximum-scale=1">
These are the only known solutions that the designers have come up with so far. But if you have another one to fix this bug, do share it with us in the comments.
