jQuery is a JavaScript library designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animation, and Ajax. It is free, open-source software using the permissive MIT License. As of May 2019, jQuery is used by 73% of the 10 million most popular websites.
Description
If you have an input field on your website with a font size of fewer than 16 pixels, Safari on iPhone considers the text too small to read and automatically zooms in on the form field when the user taps on it.
The behavior is intended but it can deteriorate the expected user experience so it might be a good idea to disable this functionality and keep the zoom static while filling form controls.
