How to Outline and Partially Fill an SVG Star Shape?

Outlining and Partially Filling an SVG Shape

Problem:

You have an SVG star shape and want to:

• Apply an outline to the outside of the star without dissecting its inner sections.
• Partially fill the star shape to indicate star ratings.

Solution:

Outlining the Star:

To outline the star without affecting its inner shape, use the stroke property. In your example, the stroke property is currently applied to every line of the star, including lines that intersect the inner area. To avoid this, modify your code as follows:

<polygon points="100,10 40,198 190,78 10,78 160,198">

Partially Filling the Star:

For partial filling, you can use a filter effect. Here's an example that uses a filter to animate the fill:

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

This filter defines a red fill that is partially filled by an animated offset effect. By adjusting the filter's parameters or creating additional filters, you can create various partial fill effects for your star ratings.
