<div class="box2"></div>
<div class="box3"></div>
<div class="box4"></div>
<div class="box5"></div>
</body>
</html>
2. relative

- 요소의 흐름을 따른다
- 자신의 흐름을 기준으로 위치 이동이 가능하다
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Document</title>
<style>
.box1 {
width: 300px;
height: 300px;
background-color: yellow;

}
.box2 {
width: 300px;
height: 300px;
background-color: red;
display: inline-block;
position: relative;
top: 100px;
left: 100px;
}
.box3 {
width: 300px;
height: 300px;
background-color: green;
display: inline-block;
}
.box4 {
width: 300px;
height: 300px;
background-color: blue;
display: inline-block;
}
.box5 {
width: 300px;
height: 300px;
background-color: bisque;
display: inline-block;
}
</style>
</head>
<body>
<div class="box1"></div>
<div class="box2"></div>
<div class="box3"></div>
<div class="box4"></div>
<div class="box5"></div>
</body>
</html>
3. absolute

- 요소의 흐름에서 벗어난다
- 부모를 기준으로 이동한다
- 자신의 위치 기준 상위의 요소 중에서 relative, absolute 등 위치 지정이 있는 부모가 없으면 body를 기준으로 한다
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Document</title>
<style>
.box1 {
width: 300px;
height: 300px;
background-color: yellow;
display: inline-block;
}
.box2 {
width: 300px;
height: 300px;
background-color: red;
display: inline-block;
position: absolute;
top: 100px;
left: 100px;
}
.box3 {
width: 300px;
height: 300px;
background-color: green;
display: inline-block;
}
.box4 {
width: 300px;
height: 300px;
background-color: blue;
display: inline-block;
}
.box5 {
width: 300px;
height: 300px;
background-color: bisque;
display: inline-block;
}
</style>
</head>
<body>
<div class="box1"></div>
<div class="box2"></div>
<div class="box3"></div>
<div class="box4"></div>
<div class="box5"></div>
</body>
</html>
absolute를 사용해 특정 요소 기준으로 움직이고 싶을 때



<div class="box4">
<div class="box5"></div>
</div>
- box5가 box4를 기준으로 움직이고 싶다
.box4 {
width: 300px;
height: 300px;
background-color: blue;
display: inline-block;
position: relative;
}
.box5 {
width: 50px;
height: 50px;
background-color: bisque;
display: inline-block;
position: absolute;
left: 50px;
bottom: 50px;
}
- box5를 absolute
- box4를 relative
4. fixed


- 요소의 흐름을 벗어남
- 화면을 기준으로 위치 이동
- 화면에 고정 되어 있음
