radiogroup 작성 사례

<div>
	<h1 id="cwork">취/창업여부</h1>
	<ul role="radiogroup" aria-labelledby="cwork">
		<li>
			<input type="radio" id="radio" id="radio_1"> <label for="radio_1">취업</label>
		</li>
		<li>
			<input type="radio" id="radio" id="radio_2"> <label for="radio_2">창업</label>
		</li>
	</ul>
</div>

특정 이유로 fieldset을 사용할 수 없다면 role=”radiogroup”, role=”group”을 적절하게 사용.
라디오가 아니라 체크박스인 경우 role="group" 사용. 

aria-labelledby
: aria-labelledby를 사용하면 어떤 요소의 레이블로서 DOM에 있는 다른 요소의 ID를 지정할 수 있습니다.
