웹디자인 기능사 퀴즈 풀기

웹 디자인 기능사 필기 기출문제를 JS를 이용해서 간단한 퀴즈 프로그램을 만들었습니다.
퀴즈의 답을 입력하고 정답 확인하기 버튼을 누르면 답이 나타나게 됩니다.


1.HTML 코드

HTML에서 js를 동작하기위한 class이름과 input등을 적절히 사용하여
사용자가 알아보기쉽게 표현해야합니다.

        <sapn class="quiz__type"></sapn>
        <h2 class="quiz__question">

            <div class="ask">

2.CSS 코드

CSS는 앞서 마크업한 HTML 코드를 디자인및 js동작할때 태그에 추가할 class를 만듭니다.

3. JS코드

Javascript 는 HTML 에서 작성한 선택자 요소를 가져와 원하는 정보를 동적을 출력해줍니다.
