The fillStyle property allows you to set the color, gradient, or pattern used to fill shapes drawn on the canvas. You can assign a color using a string like "#ff0000" for red or "rgba(52, 152, 219, 0.5)" for a semi-transparent blue. Similarly, strokeStyle sets the color, gradient, or pattern for the outlines of shapes. Both properties accept CSS color values, enabling a wide variety of visual effects.

To remove part of your drawing or reset a specific area, use clearRect(x, y, width, height). This method erases everything within the defined rectangle, allowing you to clear mistakes, update animations, or manage dynamic content efficiently. For example, calling ctx.clearRect(0, 0, canvas.width, canvas.height) will clear the entire canvas.
