--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:

<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.

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

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

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

You should not change the inner text of the Indoor label.

assert.equal(document.querySelector('label[for="indoor"]')?.innerText?.trim(), 'Indoor');

You should not change the inner text of the Loving label.

assert.equal(document.querySelector('label[for="loving"]')?.innerText?.trim(), 'Loving');
