Kann mir jemand helfen, dem Etikett eine Animation hinzuzufügen, wenn ich mit CSS auf die Eingabe klicke?

Ich habe versucht, eine Klasse namens „inputUser“ in der Eingabe zu erstellen und dann habe ich versucht, eine Animation im Label-Stil zu erstellen, aber es hat nicht funktioniert und ich weiß nicht warum. Die Animation umfasst, wenn der Benutzer auf den Camp-Text klickt, die Beschriftungen (Nome, Email, Telefone, Cidade, Estado und Endereco) ansteigen (oben: -20 Pixel), die Schriftgröße auf 12 Pixel verkleinert wird und die Farbe in grünlich wechselt. Gelb. [[Bildbeschreibung hier eingeben](https://i.stack.imgur.com/8gg3w.png)](https://i.stack.imgur.com/Z05NC.png)

我认为您正在寻找的是将标签放在输入字段的顶部，直到用户处于焦点或有数据 在输入字段内。那么您希望标签位于其上方，对吗？

我在下面附上了一个片段。

这是通过以下方式完成的：

input:not(:invalid) + label,
input:focus + label {
  top: 0;
  
  opacity: 75%;
  font-size: 0.9rem;
  
  background: white;
  
  transition: all .2s ease-in-out;
}

*{
  font-family: arial;
  padding: 0;
  margin: 0;
}

form {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  
}

.input-field {
  position:relative;
  width:204px;
}

input {
  position: relative;
  
  width: 200px;
  
  margin: 20px;
  padding: 10px 8px;
  
  outline: none;
  border: none;
  border-bottom: 2px  solid black;
  font-size:1rem;
}

input:focus {
  border-bottom: 3px solid black;
}

label {
  position: absolute;
  top: 30%;
  left: 10%;
  
  padding: 5px 10px;
  
  font-size: 1rem;
  
  pointer-events: none;
  transition: all 0.2s ease-in-out 0s;
}

input:not(:invalid) + label,
input:focus + label {
  top: 0;
  
  opacity: 75%;
  font-size: 0.9rem;
  
  background: white;
  
  transition: all .2s ease-in-out;
}
<form>
  <div class="input-field">
    <input type="text" name="forename" required>
    <label>First Name</label>
  </div>

  <div class="input-field">
    <input type="text" name="surname" required>
    <label>Last Name</label>
  </div>
</form>
