This is an Illustrator Neon outline border Graphic Style. It is vector based so it can be sized as needed without losing any detail. This could also be used for objects/shapes. I created this in Illustrator CS4 so, I’m not sure if the effects created will work with earlier versions of illustrator. It might work with CS, CS2 & CS3 but, not tested.
Graphic Styles are one-click special effects for your artwork. Graphic Styles allow you to save a collection of effects as a Style so it can be used over and over again. It is vector based so it can be sized as needed without losing detail. Some are for text, some are for any kind of object.
