### Focus Within

The psuedo class `:focus-within` gives focus to a parent element like a `form` element when `input` elements receive focus.

#### HTML

```html
  <form>
    <label for="given_name">Given Name:</label>
    <input id="given_name" type="text">
    <br>
    <label for="family_name">Family Name:</label>
    <input id="family_name" type="text">
  </form>

```

#### CSS

```css
form {
  border: 3px solid #2d98da;
  color:  #000000;
  padding: 4px;
}

form:focus-within {
  background: #f7b731;
  color: #000000;
}

```
