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.
You can try using this code :
p { text-shadow: 1px 1px 1px #000, 3px 3px 5px blue; }
