Use CSS positioning to specify how an element is positioned and where it should be located on the page.
The term "CSS positioning" typically refers to using the
position property to specify how an element is positioned. For example, you can specify whether you want the element positioned relative to its natural position in the page, in an absolute position (taken out of the normal flow), in a fixed position, etc.
This example offsets the element 80 pixels from the left of where it would have been. If we had specified
top, it would appear 80 pixels below where it would have been. It's important to note that other elements are not affected by this element's offset. Therefore, overlapping may occur.
To perform absolute positioning in CSS you again use the
position property. Only, this time you use use
position:absolute; followed by the desired offset.
Fixed positioning allows you to fix the position of an element to a particular spot on the page - regardless of scrolling.
