2. relative (위치를 옮기고 싶을 때)
static 일 때는 옮길 수 없음 / 마진은 자기만 밀리는 게 아님 다 밀림

8. 보더 크기만큼 사진 넣는 방법
* { box-sizing: border-box; }
box-sizing를 사용하면 보더, 패딩 등의 크기를 고려해서 박스 길이에 맞게 길이를 측정한다
<!DOCTYPE html>
<html lang="en">
<head>
<style>
* {
box-sizing: border-box;
}
.img-box {
width: 300px;
height: 300px;
border: 1px solid red;
padding: 10px;
margin-bottom: 10px;
}
.img-item {
width: 100%;
height: 100%;
object-fit: cover;
}
</style>
</head>
<body>
<div class="img-box">
<img src="Screenshot_1.png" class="img-item" />
</div>
<div class="img-box">
<img src="Screenshot_1.png" class="img-item" />
</div>
</body>
