Removes any box-shadow that was applied to the element.

You need at least two values:

• the first is the horizontal offset
• the second is the vertical offset

The shadow color will be inherited from the text color.

You can define a color as the last value.

As with color, you can use color names, hexadecimal, rgb, hsl...

The optional third value defines the blur of the shadow.

The color will be diffused across 10px in this example, from opaque to transparent.

The optional fourth value defines the spread of the shadow.

The spread defines how much the shadow should grow: it enhances the shadow.
