The difference between relative and absolute

Question

I am reading this article about position , and I don’t understand why in this example a relatively positioned div affects BODY, but an absolutely positioned block ignores it?
Shouldn't they behave the same when they are located inside another element?

CSS:

body {
     display: block;
     margin: 8px;
}

#box_1 { 
     position: relative;
     width: 200px;
     height: 200px;
     background: #ee3e64;
}
#box_2 { 
     position: absolute;
     top: 0;
     left: 100px;
     width: 200px;
     height: 200px;
     background: #44accf;
}

Answer 1

Basically, you have four position states that look like this:

• static (default)
• regarding
• fixed
• absolute

, "" (left:15px 15px), ( ) (left: 15px) , 15 .
