Selecting Fonts: <font>
The <font> element lets you select the font for text, as well as its size and color. This element was deprecated in HTML 4.0 in favor of style sheets, which means it's available in XHTML 1.0 Transitional and XHTML 1.0 Frameset, but not in XHTML 1.1 or XHTML 1.0 Strict. Here are this element's attributes:
- class — Sets the style class of the element. (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.)
- color — Sets the color of the text. This attribute was deprecated in XHTML 4.0. (Supported in XHTML 1.0 Transitional, and XHTML 1.0 Frameset.)
- dir — Sets the direction of directionally neutral text. This attribute can be set to ltr, for left-to-right text, or rtl, for right-to-left text. (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.)
- face — Specifies a single font name or a list of names, separated by commas. This attribute was deprecated in HTML 4.0. (Supported in XHTML 1.0 Transitional and XHTML 1.0 Frameset.)
- id — Specifies the ID with which to refer to the element. You should set this attribute to a unique identifier. (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.)
- lang — Sets the base language of the element. (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.)
- size — Specifies the size of the text, from 1 (the smallest) through 7 (the biggest). This attribute was deprecated in HTML 4.0. (Supported in XHTML 1.0 Transitional and XHTML 1.0 Frameset.)
- style — Indicates how a browser should display the element. You should set this to an inline style. (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.)
- title — Specifies the title of the body. (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.)
- xml:lang — Specifies the base language for the element when the document is treated as XML. (Supported in XHTML 1.0 Strict, XHTML 1.0 Transitional, XHTML 1.0 Frameset, and XHTML 1.1.)
This element was indeed deprecated in HTML 4.0 (you can use <div> or <span> elements instead, together with the font CSS properties), but it's still in widespread use and available in XHTML 1.0 Transitional and XHTML 1.0 Frameset, so you'll take a quick look at it here. An example is shown in Listing 11.11 and Figure 11.11. This example uses the <font> element and its attributes to specify Times New Roman font in blue.
Example 11.11. An XHTML Document That Uses the <font> Element (ch11_11.html)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<font size="4" color="blue" face="Times New Roman">
The <font> element is popular,
but don't forget that it's deprecated.
</font>
</body>
</html>
)
Figure 11.11 Using the <font> element in Internet Explorer.
The font size is set to 4 in ch11_11.html (size="4"). The <font> element lets you set the font sizes from 1 to 7, with 7 being the largest. The example in Listing 11.12 shows all the possible font sizes.
Example 11.12. An XHTML Document That Displays Font Sizes (ch11_12.html)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
