Explanation of the CSS Design

This CSS creates a stylized blackboard section on a webpage with the following layers and effects:

Google Font Import: The Fredericka the Great font is imported for a handwritten chalkboard style.
.demo-section: Sets a background image (bg-wall.jpg) to simulate a wall behind the blackboard. The image covers the section and is anchored to the bottom center. Padding ensures space around the board.
.demo-blackboard-outer-container: This is a semi-transparent white container with rounded corners and a soft shadow, giving a floating effect over the wall. It centers and constrains the blackboard area.
.demo-blackboard-inner-container: This mimics a framed blackboard:
- Rounded corners
- A thick light-gray border with layered shadows and insets to mimic depth and realism
- A solid dark background (#222) for contrast
.demo-blackboard-inner-container: This mimics a framed blackboard:
