CSS 애니메이션 - 3D cube

CSS 애니메이션 연습하기

큐브를 만들어서 3d효과로 입체적으로 만들어보겠습니다.

결과

HTML

정육면체를 만들기 위해서 div박스를 6개 만들어줍니다.

<div class="cube">
    <div>북극꼼</div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
</div>

CSS

배경색을 넣고 z축까지 위치를 설정해서 정육면체를 만들어줍니다. 그리고 각각의 면에 애니메이션을 각각 줘서 위 아래로 커졌다가 작아지는 애니메이션을 만들어줍니다.
