Contact Form Not Working Correct - HTML/CSS

Question

I got it to work the way I wanted once, but cant seem to make it work again. This image shows my desired result, and then what's happening.

Why is this happening?

This is the code that's working for me:

<div class="form">
  <input type="name" name="name" autocomplete="off" required />
  <label for="name" class="label-name"> 
      <span class="content-name"> Name </span>  

And the CSS styling:

.content-name {
  position: absolute;
  bottom: 5px;
  left: 0px;
  transition: all 0.3s ease;
}

.form input:focus + .label-name .content-name,
.form input:valid + .label-name .content-name {
  transform: translateY(-150%);
  color: #5fa8d3;
}

.form input:focus + .label-name::after,
.form input:valid + .label-name::after {
  transform: translateX(0%);
}

Code that isn't working:

<div class="form"> 
    <input type="email" name="email" autocomplete="off" required />
    <label for="name" class="label-email">
        <span class="content-email"> Email </span>
</div>

And the CSS:

.content-email {
  position: absolute;
  bottom: 5px;
  left: 0px;
  transition: all 0.3s ease;
}

.form input:focus + .label-email .content-email,
.form input:valid + .label-email .content-email {
  transform: translateY(-150%);
  color: #5fa8d3;
}

.form input:focus + .label-email::after,
.form input:valid + .label-email::after {
  transform: translateX(0%);
}

Answer 1

I'm not sure why this worked, I changed "email" to "emailaddress" in the div and its working fine now.
