The CSS text-shadow property is used to render shadows for text. Each distinct shadow gets 2 - 4 values and an optional "inset" keyword. You can create a comma separated list of distinct shadows that will apply under the same text in order to create different looking effects.
NOTE: Not all browsers adhere to this property yet. Due to this discrepency try not to rely on the shadow effects to make your text more readable, for instance when using light text on a light background. In other words just think about how your text will look if the shadows do not render, will the text still be easy to read?
Blah blah blah blah blah and more blah ...
specify shadow settings
Example: "inset 1px 2px 3px #000"
The optional inset keyword makes the shadow inset as opposed to rendering it under the text.
The first value sets the horizontal offset of the shadow.
The second value sets the vertical offset of the shadow.
The third value sets the blur radius of the shadow.
The fourth value sets the color of the shadow.
Specify that no shadow is to be on the text
