Text-shadow, for all browsers

The CSS 3 standard text shading attribute and alternative for older browsers.

The shadow effect to the characters of a text exists in Internet Explorer from the version 5.5 as a filter ActiveX. It was generalized to all browsers by becoming a property of CSS 3.

Demonstration

The standard code

The text-shadow property is followed by a definition or a list of definitions separated by a comma.

You can cancel the property with the definition: text-shadow: none.

Each definition is composed of four parameters, two of which being optional.

Color. Optional. The default is the color of the text.
Horizontal offset. The width of the shadow that extends to the right if the value is positive. A negative value add it on the left.
Vertical offset. This is the height of the shadow, down if positive, up otherwise.
Blur. Optional, defaults to 0. An integer value greater than zero makes a slightest shadow.

The code of the demo:

.tshadow {
  text-shadow: 1px 1px 2px black;
}

To surround the characters with a halo effect:

.halo {
  text-shadow: 1px 1px 2px black, 0 0 1em gray, 0 0 0.2em gray;
}
