What signifies an index position?

The index position regulates the arrangement of an element.

1. Elements with a greater index position place on top of those with a lower position
2. Offspring elements can solely place according to their progenitor element. (i.e., If element A possesses a higher index position than element B, the offspring of element B will never overlap element A)
3. Index position solely functions on relative, absolute, and fixed placement
4. The standard index position is 0

Employ an index position to arrange elements

1. Single out a div block you wish to arrange
2. Employ an index position (since the default index position is 0, any value greater than 0 will arrange an element on top)
3. Elevated values will arrange on top of lower values
4. Detrimental values can lead to elements disappearing
