What code can I use to deactivate the zoom in on my phone when I focus on the form (text input) elements in Webflow?

To deactivate the zoom in effect on mobile devices when focusing on form elements in Webflow, you can use the CSS property `user-scalable` combined with a media query.

By setting `user-scalable` to `no`, you are essentially disabling the zoom functionality on the specific element. Here's an example of how you can implement this:

```css
@media (max-width: 767px) {
input[type="text"],
input[type="email"],
textarea {
touch-action: manipulation;
user-select: none;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-scalable: no;
}
}
```

In this example, the media query `(max-width: 767px)` targets mobile devices with a maximum width of 767 pixels, which typically includes smartphones. The `input[type="text"]`, `input[type="email"]`, and `textarea` selectors target the specific form elements (text input, email input, and textarea respectively).

The `touch-action: manipulation;` line is included to improve touch responsiveness on some devices.

Additionally, the `user-select` and vendor-prefixed versions (`-webkit-user-select`, `-moz-user-select`, `-ms-user-select`) properties disable text selection on those elements if needed.

By combining all of these CSS properties, you should be able to deactivate the zoom-in effect when focusing on form elements in Webflow on mobile devices.
