강아지 애니메이션

강아지 애니메이션

PUG와 SCSS를 이용해서 강아지 애니메이션을 만들었습니다.

PUG

pug를 이용해서 코드를 만듭니다. html보다 간결한 작성이 가능합니다.
들여쓰기로 영역을 구분하기에 닫는 태그를 적을 필요가 없습니다.

.dog
.dog-body
    .dog-tail
        .dog-tail
            .dog-tail
                .dog-tail
                    .dog-tail

HTML

pug코드를 HTML코드로 컴파일한 코드.

SCSS

SCSS를 이용해서 코드를 만듭니다. css보다 간결한 작성이 가능합니다.
scss는 sass컴파일러를 이용한 좀 더 기존의 css구조와 비슷한 형태의 방법입니다.

$dog-width: 100px;
$interval: 200ms;
$color-gray: #eaebec;
$easing: ease-in-out;

body {
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
}

html, body {
    background: #FFE16E;
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
}

*, *:before, *:after {
    box-sizing: border-box;
    position: relative;
}

// dog
.dog {
    width: $dog-width;
    height: $dog-width;
    z-index: 1;
    
    &:before {
        content: '';
        display: block;
        position: absolute;
        width: 100%;
        height: 100%;
        border-radius: 50%;
        background: rgba(black, 0.03);
        transform: translatey(-30%) scale(1.5);
    }
    
    * {
        position: absolute;
    }
}

.dog-body {
    border-radius: 50%;
    background: white;
    position: absolute;
    width: 100%;
    height: 100%;
}

// dog-body
.dog-body {
    top: -50%;
    
    &:before {
        content:'';
        position: absolute;
