HTML and CSS, but without Javascript

Scenario: Create a form that has two steps for reading user input and you don’t want to hide and show elements with javascript. You can still do it with plain HTML and CSS.

<div class="container">
  <div class="rating">
    <input name="rating" type="radio" /> 1
    <input name="rating" type="radio" /> 2
    <input name="rating" type="radio" /> 3
    <input name="rating" type="radio" /> 4
    <input name="rating" type="radio" /> 5
  </div>
  
  <textarea name="feedback"></textarea>
</div>

.container textarea { display:none; }
.container:has(.rating > input:checked) .rating { display:none; }
.container:has(.rating > input:checked) textarea { display:block; }
