Class Project Description: Create an Animated Rectangle with CSS

n this hands-on class project, you will apply the knowledge and skills you've gained in the course to create an animated rectangle using CSS. The goal is to design a rectangle that animates based on specific properties such as size, color, or position. This project will help you understand how to use CSS keyframes and animation properties to bring elements to life with smooth transitions. Here's how to go about it:

Project Steps:

1. Understand the Requirements:

   • The objective is to create a simple rectangle that animates over time. You will control properties such as its size, color, and position using CSS animations.

2. Set Up Your HTML and CSS Environment:

   • Create an HTML file that contains a div element to represent the rectangle. This div will be animated with CSS keyframes.

3. Write the CSS Animation:

   • In a separate CSS file (e.g., animation.css), style the rectangle and define its animation using keyframes.

4. Enhance the Animation:

   • Add more properties to animate, such as rotation, opacity, or border-radius.

5. Test Your Animation:

   • Test the animation by viewing the HTML file in your browser. Observe how the rectangle changes in size, position, and color, and make sure the animation runs smoothly.

6. Document Your Code:

   • Write comments in your CSS code to explain the animation properties used and how the @keyframes rule works to animate the rectangle.

7. Final Submission:

   • Compile all your work into a comprehensive Word document. The document should include your HTML and CSS code, explanations of each part, and screenshots showing the animation at different stages.

Submission Instructions:

1. HTML and CSS Code: Include the complete HTML and CSS code with comments explaining how you created the animated rectangle.
2. Keyframe Animation: Show the keyframes you defined and explain how they control the rectangle’s animation.
3. Testing: Provide screenshots showing the rectangle at various stages of its animation.
4. Documentation: Ensure all code is well-commented and explanations are clear.

Project Benefits: Completing this class project will empower you to:

• Understand how to use CSS keyframes to create smooth animations.
• Gain practical experience in working with CSS animation properties like transform, opacity, and background-color.
• Develop problem-solving skills by animating different aspects of a webpage element.
• Learn to document your code effectively, making it easier to understand and maintain.

By the end of this project, you will have created a fully animated rectangle using CSS, showcasing your ability to add dynamic visual effects to webpages.
