How can I partially fill an SVG star using a filter for a star rating system?

Creating and Partially Filling SVG Stars

In the provided SVG example, the star shape is outlined with blue, and the lines dissect the inner shape. Additionally, the user wants to partially fill the star shape, with potential uses for star ratings.

Outlining the Star

To create the outline, the code uses CSS style attributes:

style="fill:red;stroke:blue;"

The "fill" attribute specifies the color of the shape's interior, while the "stroke" attribute specifies the color of the outline.

Partially Filling the Star

Partial filling can be achieved using a filter in SVG. The filter defines how the graphic is rendered, and the following code adds a filter that partially fills the star shape:

<filter></filter>

The filter first applies a red flood to the entire area, then uses an offset and an animation to gradually decrease the offset, which has the effect of gradually revealing the inner shape.

This filter is then applied to the using the filter attribute:

<polygon filter="url(#fillpartial)" points="165.000, 185.000..."></polygon>
