Creates a styled radio button with animation on state change.

- Create a `.radio-container` and use flexbox to create the appropriate layout for the radio buttons.
- Reset the styles on the `<input>` and use it to create the outline and background of the radio button.
- Use the `::before` element to create the inner circle of the radio button.
- Use `transform: scale(1)` and a CSS transition to create an animation effect on state change.

```html
<div class="radio-container">
  <input class="radio-input" id="apples" type="radio" name="fruit" />
  <label class="radio" for="apples">Apples</label>
  <input class="radio-input" id="oranges" type="radio" name="fruit" />
  <label class="radio" for="oranges">Oranges</label>
</div>
```
