Changes the appearance of a form if any of its children are focused.
|
|
|
|
```html
|
|
<form>
|
|
<label for="username">Username:</label>
|
|
<input id="username" type="text" />
|
|
<br />
|
|
<label for="password">Password:</label>
|
|
<input id="password" type="text" />
|
|
</form>
|
|
```
|
|
|
|
```css
|
|
form {
|
|
border: 2px solid #52B882;
|
|
padding: 8px;
|
|
border-radius: 2px;
|
|
}
|
|
|
|
form:focus-within {
|
|
background: #7CF0BD;
|
|
}
|
|
|
|
label {
|
|
display: inline-block;
|
|
width: 72px;
|
|
}
|
|
|
|
input {
|
|
margin: 4px;
|
|
}
|
|
```

#### Explanation
|
|
|
|
- The psuedo class `:focus-within` applies styles to a parent element if any child element gets focused. For example, an `input` element inside a `form` element.
