Summary

In this hour you learned that a style sheet can control the appearance of many HTML pages at once. It can also give you extremely precise control over typography, spacing, and the positioning of HTML elements. You also learned that by adding a style attribute to almost any HTML tag, you can control the style of any part of an HTML page without referring to a separate style sheet document.

Table 12.1 summarizes the tags discussed in this hour. Refer to the CSS1 and CSS2 style sheet standards at www.w3c.org for details on what options can be included after the <style> tag or the style attribute.

Table 12.1. HTML Tags and Attributes Covered in Hour 12
Tag/Attributes	Function
`<style>`…`</style>`	Allows an internal style sheet to be included within a document. Used between `<head>` and `</head>`.

Attribute
`type="contenttype"`	The Internet content type. (Always `"text/css"` for a CSS style sheet.)
`<link />`	Links to an external style sheet (or other document type). Used in the `<head>` section of the document.

Attribute
`href="url"`	The address of the style sheet.
`type="contenttype"`	The Internet content type. (Always `"text/css"` for a CSS style sheet.)
`rel="stylesheet"`	The link type. (Always `"stylesheet"` for style sheets.)
`<span>`…`</span>`	Does nothing at all except provide a place to put `style` or other attributes. (Similar to `<div>`…`</div>` but does not cause a line break.)

Attribute
`style="style"`	Includes inline style specifications. (Can be used in `<span>`, `<div>`, `<body>`, and most other HTML tags.)
