Describe how CSS custom properties (CSS Variables) can be used to streamline the management of color schemes in a stylesheet.
- CSS Variables cannot be used for managing color schemes.
- They allow you to define a color only once and reuse it throughout the stylesheet.

To evenly distribute space around flex items, the property justify-content should be set to ________.

What is the difference between opacity and alpha transparency in CSS color definitions?
- Opacity is applied to block-level elements, while alpha transparency is for inline elements.
- Opacity is controlled by the opacity property, while alpha transparency is controlled by the transparent keyword.
