• Background Position: Specifies the starting position of a background image or color. It can be set using keywords or specific values.
• Utility Classes: Tailwind CSS offers predefined utility classes for common background positioning.

Background Position Values

The values can be set using:

• Percentages: E.g., bg-[25%], bg-[50%].
