Create a detailed step-by-step guide on how to implement a smooth, animated wave effect using CSS and HTML. Include [NUMBER_OF_WAVES], [ANIMATION_DURATION], and [WAVE_COLOR] as customizable parameters. Explain the use of keyframes, bezier curves for easing, and how to optimize performance for different browsers. Provide code snippets with comments for clarity. Ensure the effect is responsive and works on mobile devices. Optionally, suggest ways to enhance the wave effect using SVG or JavaScript for more complex interactions.
