<title>CSS Backgrounds Test: box-shadow in 3 sub-tests with not inset and Npx 0px</title>
<link rel="author" title="Gérard Talbot" href="http://www.gtalbot.org/BrowserBugsSection/css21testsuite/">
<link rel="help" href="https://www.w3.org/TR/css-backgrounds-3/#the-box-shadow">

<!--
<shadow> = inset? && <length>{2,4} && <color>?
A comma-separated pair of numbers in curly braces {A,B}
indicates that the preceding type, word, or group occurs
at least A and at most B times.
A question mark (?) indicates that the preceding type,
word, or group is optional (occurs zero or one times).
The components of each <shadow> are interpreted as follows:
1st <length>
Specifies the horizontal offset
of the shadow. A positive value draws a shadow that is offset to
the right of the box, a negative length to the left.
2nd <length>
Specifies the vertical offset
of the shadow. A positive value offsets the shadow down, a negative one up.
4th <length>
Specifies the spread distance.
Positive values cause the shadow to expand in all directions
by the specified radius.
Negative values cause the shadow to contract.
