text-shadow

Summary

The text-shadow 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.

This property applies to both ::first-line and ::first-letter pseudo-elements.

Syntax

/* offset-x | offset-y | blur-radius | color */
text-shadow: 1px 1px 2px black; 

/* color | offset-x | offset-y | blur-radius */
text-shadow: #CCC 1px 0 10px; 

/* offset-x | offset-y | color */
text-shadow: 5px 5px #558ABB;

/* color | offset-x | offset-y */
text-shadow: white 2px 5px;

/* offset-x | offset-y
/* Use defaults for color and blur-radius */
text-shadow: 5px 10px;

/* Global values */
text-shadow: inherit;
text-shadow: initial;
text-shadow: unset;

Values

<color>

Optional. Can be specified either before or after the offset values. If the color is not specified, a UA-chosen color will be used.

Note: If you want to ensure consistency across browsers, explicitly specify a color.

<offset-x> <offset-y>

Required. These <length> values specify the shadow's offset from the text. <offset-x> specifies the horizontal distance; a negative value places the shadow to the left of the text. <offset-y> specifies the vertical distance; a negative value places the shadow above the text. If both values are 0, then the shadow is placed behind the text (and may generate a blur effect when <blur-radius> is set).
To find out what units you can use, see <length>.</length>

<blur-radius>

Optional. This is a <length> value. If not specified, it defaults to 0. The higher this value, the bigger the blur; the shadow becomes wider and lighter.</length>

Formal syntax

none | <shadow-t>#
where 
<shadow-t> = [ <length>{2,3} && <color>? ]
where 
<color> = <rgb()> | <rgba()> | <hsl()> | <hsla()> | <hex-color> | <named-color> | currentcolor | <deprecated-system-color>
where 
<rgb()> = rgb( <rgb-component>#{3} )
<rgba()> = rgba( <rgb-component>#{3} , <alpha-value> )
<hsl()> = hsl( <hue>, <percentage>, <percentage> )
<hsla()> = hsla( <hue>, <percentage>, <percentage>, <alpha-value> )
<named-color> = <ident>
<deprecated-system-color> = ActiveBorder | ActiveCaption | AppWorkspace | Background | ButtonFace | ButtonHighlight | ButtonShadow | ButtonText | CaptionText | GrayText | Highlight | HighlightText | InactiveBorder | InactiveCaption | InactiveCaptionText | InfoBackground | InfoText | Menu | MenuText | Scrollbar | ThreeDDarkShadow | ThreeDFace | ThreeDHighlight | ThreeDLightShadow | ThreeDShadow | Window | WindowFrame | WindowText
where 
<rgb-component> = <integer> | <percentage>
<alpha-value> = <number>
<hue> = <number>

Specifications

Browser compatibility

[1] Gecko theoretically supports infinite text-shadows (don't try it). Gecko 2 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1) and later cap the blur radius at 300 for performance reasons. If the <color> value is unspecified, then Gecko uses the value of the element's color property.

[2] Opera supports a maximum of 6-9 text-shadows for performance reasons. The blur radius is limited to 100px. Opera 9.5 to 10.1 adheres to the old, reverse painting order (CSS2, the first specified shadow is on the bottom).

[3] Internet Explorer 5.5 supports Microsoft's Shadow and DropShadow Filter.

[4] In Safari, any shadows that do not explicitly specify a color are transparent. Safari 1.1 to 3.2 only supports one text-shadow (displays the first shadow of a comma-separated list and ignores the rest). Safari 4.0 (WebKit 528) and later support multiple text-shadows.
Konqueror supports text-shadow starting with version 3.4.
