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   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>

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.

Issue

Currently you are moving all the floating labels up when any of the input values are either focused or valid.

input:focus ~ #floating-label,
input:not(:focus):valid ~ #floating-label{
  //...
}

Solution

To fix that, you couldadd the same id or something similar like input-field-X to the input tags. This isn't great for your css though, as it has to be repeatable and it grows quickly. So I would just create a single <div lang-html prettyprint-override"> <div > <div > <input type="text" name="name" required> <label for="name">Your name</label> </div> <div > <input type="text" name="email" required> <label for="name">Your email</label> </div> <div > <input type="text" name="subject" required> <label for="name">Subject</label> </div> </div>

I also fixed your CSS a bit.

html,
body {
  margin: 0;
}
body * {
  box-sizing: border-box;
}

.input-field {
  --input-field-height: 50px;
  --input-field-padding-left: 10px;
  position: relative; /* this is important for the positioning of the label*/
  width: 600px;
  height: var(--input-field-height);
  margin: 15px;
}

.input-field input {
  transition: 25ms box-shadow ease-in-out;
  width: 100%;
  height: 100%;
  padding-left: var(--input-field-padding-left);
}

.input-field label {
  position: absolute;
  top: calc(var(--input-field-height) / 2);
  transform: translateY(-50%);
  left: 20px;
  font-family: "Merriweather Sans", sans-serif;
  font-weight: 300;
  font-size: 16px;
  pointer-events: none;
  color: #777;
  background: white;
  transition: 0.2s ease all;
}
.input-field input:focus ~ label,
.input-field input:not(:focus):valid ~ label {
  top: 0;
  left: var(--input-field-padding-left);
  color: #8c7d50;
}

.input-field input:focus {
  outline: 1px solid yellowgreen; /* using outline istead of the border doesn't change the size of the input field */
  box-shadow: 0 0 0 1px #8c7d50;
}
