The glow font effect renders a blurred outline around the text.

Both the outline pass and the subsequent blur pass can be controlled independently. Additionally, an offset can be applied which makes the effect suitable for generating drop shadows as well.

The effect is declared as:

font-effect: glow( <width-outline> <width-blur> <offset-x> <offset-y> <color> );

Its properties are specified by the following.

width-outline

Determines the outline width of the effect.

width-blur

Determines the blur width of the effect. For negative specified values, the used value will be copied from width-outline.

offset-x

offset-y

These properties define the offset, in pixels, between the source text and the glow.

color

The color is applied multiplicatively over the entire effect.
