Question

An element with position: relative; is positioned relative to its normal position.

Setting the top, right, bottom, and left properties of a relatively-positioned element will cause it to be adjusted away from its normal position. Other content will not be adjusted to fit into any gap left by the element.

Here is the source: CSS Positioning

Now,how can I make relative position to work as viewport and adjust accordingly by setting height,width etc like fixed position. It is possible in css or not? If not then how can I do?

Answer 1

Try it:

div{
POSITION: relative; 
TOP: 450px; LEFT: 651px; 
width: calc(100% - 651px);
float: left;
}

You can also use javascript or jquery to do it.
