How to Unzoom Page When Input Field is Focused on Mobile?

I’m currently fixing a few things on the mobile side of my website using and have encountered a slight usability issue. When a user selects an input field on mobile, the page zooms in, which I like. When the user is done though it leaves it totally zoomed in. Is there a way to unzoom the app with a double tap to the page or automatically after the user done with the input field?

If only does this when input font is under 16

I want to keep the zoom function I like it but I want it to reset native zoom after user is done with the input.
