text-shadow

The text-shadow CSS property adds shadows to text. It accepts a comma-separated list of shadows to be applied to the text and text-decorations of the element.
 
Each shadow is specified as an offset from the text, along with optional color and blur radius values.
 
Multiple shadows are applied front-to-back, with the first-specified shadow on top.
