# --description--

You can set a checkbox or radio button to be checked by default using the `checked` attribute.

To do this, just add the word `checked` to the inside of an input element. For example:

```html
<input type="radio" name="test-name" checked>
```

# --instructions--

Set the first of your radio buttons and the first of your checkboxes to both be checked by default.

# --hints--

Your first radio button on your form should be checked by default.

```js
assert($('input[type="radio"]').prop('checked'));
```

Your first checkbox on your form should be checked by default.

```js
assert($('input[type="checkbox"]').prop('checked'));
```
