Create another radio button below the first one. Nest it inside a label element with Outdoor as the label text. Give the radio button an id attribute with outdoor as the value.

--hints--

Only the original Indoor radio button input should have an id set to indoor. You can restart the step to get the original HTML back if needed.

js
assert(document.querySelectorAll('#indoor').length < 2);

You should not make any changes to the Indoor radio button. You can restart the step to get the original HTML back if needed.

js
const indoorInput = document.querySelectorAll('#indoor');
assert(
  indoorInput.length == 1 &&
  indoorInput[0]?.nodeName?.toUpperCase() === 'INPUT' &&
  indoorInput[0]?.type === 'radio' &&
  code.match(/<label\s*>\s*<input [^>]*(id=["']?indoor["']?)[^>]*>\s*Indoor\s*<\/label>/)
);

You should add exactly one new input element nested in a new label element. Make sure your new label has both an opening and closing tag.

js
assert(document.querySelectorAll('label input').length === 2);

You should not add any attributes to either opening label tag.

js
assert(code.match(/<label\s*>/g).length === 2);

Your new input should have an id attribute with the value outdoor.

js
assert(document.querySelector('label input[id="outdoor"]'));

Your new input should have a type attribute with the value radio.

js
assert(document.querySelector('label input[id="outdoor"][type="radio"]'));

You should not add any new elements other than an input nested in a label.

js
assert(document.querySelector('label input[id="outdoor"]:only-child'));

There should be no text to the left of your new input.

js
const outdoorBtn = document.querySelector('label input[id="outdoor"]');
assert(
    outdoorBtn?.previousSibling?.nodeName !== '#text' ||
    outdoorBtn?.previousSibling?.nodeValue?.replace(/\s/g, '') === ''
);

The label text for your new radio button must be exactly Outdoor. This includes capitalization.

js
assert(document.querySelector('label > input[id="outdoor"]')?.nextSibling?.nodeValue?.replace(/^\s+|\s+$/g, '') === 'Outdoor');

Your new radio button and label should be immediately below/after the Indoor radio button and label. There should be no other tags between them.

js
assert(code.match(/<\/label>\s*<label\s*>\s*<input [^>]+>\s*Outdoor/i));
