XML parsers allow you to code faster by giving you a parser for your all your XML documents (with and without DTDs).

XML documents are easily committed to a persistence layer

XML documents may be stored in files or databases. When stored in files, XML documents are simply plain text files with tags (and possibly DTDs). It is very easy to save your XML documents to a text file and pass the text file around to other machines, platforms and programs (as long as they can understand the data). In the worst case scenario, XML documents (files) can be viewed in a text editor on just about any platform.

XML documents are also naturally committed to a database (relational or object) or any other kind of XML document store. There are commercial products available which allow you to save XML documents to an XML storage layer (which is not a database per se), like Datachannel's XStore and ODI's eXcelon. These XML store solutions are quite expensive ($10,000 to $20,000 range).

talked about a lot of floating behavior, so there's only one more thing to discuss. You won't always want your content to flow past a floated element -- in some cases, you'll specifically want to prevent it.

If you have a document that is grouped into sections, you might not want the floated elements from one section hanging down into the next. In that case, you'd want to set the first element of each section to prohibit floating elements from appearing next to it. If it might otherwise be placed next to a floated element, it will be

With borders, just as with margins, the browser's calculations for line-breaking are not directly affected by any box properties set for inline elements. The only effect is that the space taken up by the borders may shift portions of the line over a bit, which may in turn change which word is at the end of the line. Turn to Figure 7-54 to see what happens when an inline element with a border is displayed across multiple lines:

B {border: 3px solid gray; background: silver;}
the only real difference that here, the uppercase letters are of different sizes. That's true, but the reason that small-caps is declared using a font property is that some fonts have a specific small-caps face. Thus, a font property is used to select that face.

What happens if no such face exists? There are two options provided in the specification. The first is for the user agent to create a small-caps face by scaling uppercase letters on its own. The second is simply to make all letters uppercase and the same size, exactly as of other elements, nor does their content flow around the positioned element. This implies that an absolutely positioned element may overlap other elements, or be overlapped by them. (We'll see how you can affect the overlapping order at the end of the chapter.)

Remember that the containing block of an absolutely positioned element is not necessarily its parent element. In fact, it often is not, unless the author takes steps to correct this situation. Fortunately, that's easy to do. Just pick the element that you want to use as the containing block for the absolutely positioned

1.4.2. The STYLE Element

The STYLE element, which is a relatively newelement in HTML, is the most common way to definea style sheet, since it appears in the document itself.STYLE should always use the attributeTYPE; in the case of a CSS1 document, the correctvalue is text/css, just as it was with
