Positions

1. position : static
The default positioning for all elements is position:static, which means the element is not positioned and occurs where it normally would in the document.
Normally you wouldn't specify this unless you needed to override a positioning that had been previously set.
#div-1{
position:static
}

2. position : relative
If you specify position:relative, then you can use top or bottom, and left or right to move the element relative to where it would normally occur in the document.
Notice the space where div-1 normally would have been if we had not moved it: now it is an empty space. The next element (div-after) did not move when we moved div-1. That's because div-1 still occupies that original space in the document, even though we have moved it.


#div-1 {
 position:relative;
 top:20px;
left:20px;
}
example Link : relative

3. position : absolute
When you specify position:absolute, the element is removed from the document and placed exactly where you tell it to go.
Let's move div-1a to the top right of the page:
#div-1 { position:absolute; top:0; right:0; width:200px;}
Notice that this time, since div-1a was removed from the document, the other elements on the page were positioned differently: div-1b, div-1c, and div-after moved up since div-1a was no longer there.
example link: absolute

4.position : relative+absolute

If we set relative positioning on div-1, any elements within div-1 will be positioned relative to div-1. Then if we set absolute positioning on div-1a, we can move it to the top right of div-1:
#div-1 {
 position:relative;
}
#div-1a {
 position:absolute;
 top:0;
 right:0;
 width:200px;
}
exaplelink: relative+absolute
