be the distance from the left inner edge to the right inner edge, andthe height is the distance from the inner top tothe inner bottom. These are both, not coincidentally, properties thatcan be applied to an element.

The various widths, heights, padding, margins, and borders allcombine to determine how a document is laid out. In most cases, theheight and width are automatically determined by the browser, basedon the available display region and other factors. Under CSS, ofcourse, you can assert more direct control over the way elements are

XHTML: What is XML?

XML (Extensible Markup Language) is a “super” markup language from which programmers can develop other, custom markup languages and specialized applications. XHTML (Extensible Hypertext Markup Language) is one such markup language.

Programmers already use XML for database and catalog work, and XML also acts as the foundation for standard web protocols including Scalable Vector Graphics (SVG), Synchronized Multimedia Integration Language (SMIL), Wireless Markup Language (WML), and Platform for Privacy Preferences (P3P).

For information about these web protocols, visit W3C.

If an external style sheet is sent using the wrong MIME type, thestyle sheet gets mangled into something unusable. If you find thatyou're having this problem, then you'll need to contactyour ISP and explain the problem. If they refuse to fix it, tryexplaining to them that IANA (the Internet Assigned NumbersAuthority, which also approves MIME types) has approved.css as the extension for the MIME typetext/css, and the slideshow mapping is not arecognized IANA MIME type.

If you wish to suppress the display of bullets altogether, then none is the value you seek. none will cause the user agent to refrain from putting anything where the bullet would ordinarily be, although it does not interrupt the counting in ordered lists. Thus, the following markup would have the result shown in Figure 7-80:

OL LI {list-style-type: decimal;}
LI.off {list-style-type: none;}
<OL>effect on the image's inline box, which is in this case
30px tall.

Nonetheless, an inline replaced element still has a value for line-height. Why? In order to be able to correctly position the element if it's been vertically aligned. Recall that, percentage values for vertical-align are calculated with respect to an element's line height. Thus:

P {line-height: 18px;}this method works. It's really the same as the last method: it
just uses a different number system. If you have to pick between the
two, use whichever makes you more comfortable.

So, similar to the way you can specify a color using three numbers from to 255, you can specify one using three hex pairs. If you have a calculator that converts between decimal and hexadecimal, then making the jump should be pretty simple. If not, it might be a little more complicated. (Of course, you could just not use this method, but that
