-
-<!-- #include src=properties/text-shadow.srb -->
-
-<P>This property accepts a comma-separated list of shadow effects to
-be applied to the text of the element. The shadow effects are applied
-in the order specified and may thus overlay each other, but they will
-never overlay the text itself. Shadow effects do not alter the size of
-a box, but may extend beyond its boundaries.  The <A
-href="visuren.html#stack-level">stack level</a> of the shadow effects
-is the same as for the element itself.
-
-<P>Each shadow effect must specify a shadow offset and may optionally
-specify a blur radius and a shadow color.
-
-<P>The syntax for 
-<span class="index-def" title="&lt;shadow-effect&gt;::definition
-of"><a name="value-def-shadow-effect">&lt;shadow-effect&gt;</a></span>
-is the following:</P>
-
-<PRE>
- &lt;color&gt;? &lt;length&gt; &lt;length&gt; &lt;length&gt;? | 
- &lt;length&gt; &lt;length&gt; &lt;length&gt;? &lt;color&gt;?
-</PRE>
-
-<P>A shadow offset is specified with two <span class="index-inst"
-title="&lt;length&gt;"><span
-class="value-inst-length">&lt;length&gt;</span></span> values that
-indicate the distance from the text. The first length value
-specifies the horizontal distance to the right of the text. A negative
-horizontal length value places the shadow to the left of the text. The
-second length value specifies the vertical distance below the text. A
-negative vertical length value places the shadow above the text.
-
-<P>A blur radius may optionally be specified after the shadow offset.
-The blur radius is a length value that indicates the boundaries of the
-blur effect. The exact algorithm for computing the blur effect is not
-specified.
-
-<P>A color value may optionally be specified before or after the
-length values of the shadow effect. The color value will be used as
-the basis for the shadow effect. If no color is specified, the value
-of the <span class="propinst-color">'color'</span> property will be
-used instead.
-
-<P>Text shadows may be used with the <a
-href="selector.html#first-letter"> :first-letter</a> and <a
-href="selector.html#first-line">:first-line</a> pseudo-elements.
-
-<div class="example">
-
-<P>The example below will set a text shadow to the right and below the
-element's text. Since no color has been specified, the shadow will
-have the same color as the element itself, and since no blur radius is
-specified, the text shadow will not be blurred:</p>
-
-<PRE>
-H1 { text-shadow: 0.2em 0.2em }

-<P>The next example will place a shadow to the right and below
-the element's text. The shadow will have a 5px blur radius and will be
-red.

-
-<P>The next example specifies a list of shadow effects. The first
-shadow will be to the right and below the element's text and will be
-red with no blurring. The second shadow will overlay the first shadow
-effect, and it will be yellow, blurred, and placed to the left and
-below the text. The third shadow effect will be placed to the right
-and above the text. Since no shadow color is specified for the third
-shadow effect, the value of the element's <span
