Contact Form Input Animation Bug

I recently asked a question about a contact form animation (the label text moves up when the box is clicked) and while I got the animation to work properly, I’ve run into a bug:

When I click on either the first and second boxes (not the third for some reason), it activates the animation for the rest of the boxes which is very annoying.

How can I get it so that when clicking on one box, it ONLY animates the box I clicked on and not the rest?

<div class="contact-col"  style="position:relative display:inline;" >

        <input type="text" name="name" required>
         <span id="floating-label">Yourname</span>

        <input type="email" name="email" required>
        <span id="floating-label-1">Your email</span>
                    
        <input type="text"  name="subject"  required>
        <span id="floating-label-2">Subject</span>
</div>

>Solution :

This is an issue since you do not explicitly pick the inputs. As a result, if you selects your inputs by name, the problem will be resolved.
