How can I create a partially filled SVG star with an outline using CSS filters?

Outlining and Partially Filling an SVG Shape

In the interest of creating an SVG star as illustrated by the example provided, an outline along with different fill options can be effectively implemented.

Regarding the outline, it's important to note that it will appear on all line segments that dissect the inner shape. To half-fill the star shape, consider using a CSS filter.

The following code demonstrates how to outline the star and partially fill it using CSS filters:

<svg height="210" width="500">
  <defs>
    <filter>

This code snippet utilizes a filter with an ID of "fillpartial" which remains constant throughout the bounding box area. It employs a few filter effects:

1. Flood Effect ("feFlood"): Fills the entire shape with a solid red color.
2. Offset Effect ("feOffset"): Moves the shape in a specific direction (vertically in this case) and changes the "dy" value of the offset effect over time through an animation. This creates the half-filled effect.
3. Composite Effects ("feComposite"): Combine the original shape with the modified offset shape to generate the final result.

It's noteworthy that this filter effect allows for a dynamic and animated partial fill, which can be desirable in various scenarios, such as star ratings.
