Description
input.
Each of your radio buttons can be nested within its own label element. By wrapping an input element inside of a label element it will automatically associate the radio button input with the label element surrounding it.
All related radio buttons should have the same name attribute to create a radio button group. By creating a radio group, selecting any single radio button will automatically deselect the other buttons within the same group ensuring only one answer is provided by the user.
Here's an example of a radio button:
<label>
<input type="radio" name="indoor-outdoor">Indoor
</label>
It is considered best practice to set a for attribute on the label element, with a value that matches the value of the id attribute of the input element. This allows assistive technologies to create a linked relationship between the label and the child input element. For example:
<label for="indoor">
<input id="indoor" type="radio" name="indoor-outdoor">Indoor
</label>
Instructions
label element. One should have the option of indoor and the other should have the option of outdoor. Both should share the name attribute of indoor-outdoor to create a radio group.

- text: Your page should have two radio button elements.
testString: assert($('input[type="radio"]').length > 1);

testString: assert($('input[type="radio"]').filter("[name='indoor-outdoor']").length > 1);
- text: Each of your two radio button elements should be nested in its own <code>label</code> element.
testString: assert($('label > input[type="radio"]:only-child').length > 1);
- text: Each of your <code>label</code> elements should have a closing tag.
testString: assert((code.match(/<\/label>/g) && code.match(/<label/g) && code.match(/<\/label>/g).length === code.match(/<label/g).length));
- text: One of your radio buttons should have the label <code>indoor</code>.
testString: assert($("label").text().match(/indoor/gi));
- text: One of your radio buttons should have the label <code>outdoor</code>.
testString: assert($("label").text().match(/outdoor/gi));
