Foundation of Order

position: static is the natural state of any element. Elements are arranged one after another in the order they're written in HTML.

What You Need to Know:

Ignoring coordinates: The properties top, right, bottom, left, and z-index do not work on static elements. This is the most common beginner mistake — trying to move text without changing its positioning type.
Zero layer specificity: Static elements are always on the lowest rendering layer.

Note

Consider this the " gravity " of the web. Elements simply fall on top of each other top to bottom (for blocks) or line up in a queue (for text).
