1/*hey guys if you have doubt how absolute property works, it works in way that 
2it  comes out of the 'document flow' i.e) just consider two div elements in
3which each a size of a box, say that you need two place the second box over the 
4top box simple just give it absolute position such that the second div 
5positioned itself with respect to the browser window, you can move the element 
6anywhere in the window*/
7div{
8  position:absolute;
9  top:10px; /*it pushes away div element from top 10px down Remember with
10  browser window*/
11  left:20px;
12  right:10px;
13  bottom:20px; 
14  /*last three property excatly similar to top property it just pushes away 
15  from specified direction*/
16}
17Wondering how to use absolute property within a div simple?
18Say you have a div inside a div. /*most case scenario*/
19putting first div relative and mentioning second div absolute will do the job
20In my early days of css, I wonder the position property with relative and no top
21bottom, right left property with it. One day I realized it.
22/*highly recommed you to run the following code two know the difference*/
