Adding a Text Drop Shadow


The drop shadow is a time-honored method for adding depth and texture to two-dimensional designs. Apple's Safari browser has included the text-shadow property, which is part of CSS3 (Table 4.5), allowing you to define the color, offset (x and y), and blur for a drop shadow behind any text. Although this will not work in any browser except Safari, it will not interfere with other browsers either.

In this example (Figure 4.5), the level 1 heading has a nice reddish glow behind it, while other text has different drop shadows to make them stand out.

Figure 4.5. The title has a reddish glow beneath it, while the author's name and chapter number have a drop shadow.


To define the text shadow:

1.

text-shadow:


Type the text-shadow property name, followed by a colon (:), in the CSS definition list (Code 4.5).

Code 4.5. The drop-shadow property allows you to set the x,y offset and the blur radius.

Type a space and then a color value for the shadow. See "Values and Units Used in this Book" in the Introduction for more detail on color values.

3.

10px 12px


Type a space and then two positive or negative length values separated by a space. The first value is the vertical distance to offset the shadow (positive is down; negative is up). The second value is the horizontal offset (positive is right; negative is left).

4.

6px;


Type a space and then a positive length value for the amount of blur to apply to the shadow.

Tips

  • Keep in mind that although this is a "shadow" you can use any color for the shadow. Thus, if your text is on a dark background, you could use a light color to create a drop "glow" instead.

  • Although this example uses several different shadow strengths, colors, and offsets, if you want to make the shadows look natural, their offsets should all be proportional to each other.

  • The W3C is also suggesting the inclusion of a box-shadow property in CSS3 that works a lot like the text-shadow property, but would be applied to the elements box. This property is not implemented in any browser currently.

  • Text shadows are great way to have links pop-off the page when used with the :hover pseudo class.

  • The text-shadow property actually allows for multiple shadows on a single element. A comma separates each value list. However, Safari does not support this feature.
