What are the ways to align position:absolute?

Question

css

Hi everybody!
What are the ways to align a block with position:absolute.
There is right, top, left, bottom. I would like to know, maybe people still somehow equalize.
The bottom line is that in the absence of the property right. The block becomes as it should, that is, the indent of the parent is taken into account. But when I put right: 0, then the countdown goes from the edge of the window. You want the block to be right-aligned.
Here is a photo with no right. All parent margins are present

When using right:0

As needed

The code of the block to be aligned

width: 400px;
    padding: 20px 20px 0 20px;
    background: #fff;
    border: 1px solid #eaeaea;
    top: 62px;
    right: 0;
    position: absolute;
    z-index: 10;

Parent

padding-right: 10px;
    padding-left: 10px;
    margin-right: auto;
    margin-left: auto;

Answer 1

position relative to the parent add.

Answer 2

position: absolute | fixed | relative | static | inherit

inherit - inherits the value of the parent.

Answer 3

margin , padding ?
