Stacking Contexts In CSS

Stacking Context :

• It is a group of elements positioned on the Z-axis.
• Stacking Contexts can be nested within other stacking contexts and z-index values are used to determine the layering of elements within the same stacking context parents
• Positive z-index values indicate that the element is more toward the screen
• Negative z-index values indicate that the element is away from the screen ( refer the cover image)
