While clicking on form input field, the form is getting shrink, how to disable it?

I need some solutions for Android Devices.

I tried the below possibilities:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" />


font-size:16px;


Is there any possibilities to fix it?

Not sure I understand, do you mean this is normal behavior for INPUT fields in Android browsers? If not, we need to see the code for a page where it happens.

(When I click on a normal form field, my Android browsers open the keyboard, which covers most of the screen.)
