•E.g.
<h1 style="color:blue; text-align:center">This is a header</h1>
<p style="color:green">This is a paragraph.</p>
•The name-value pairs in the style definition are actually CSS property/value pairs.

The style is defined in the head section of the document, similar to the following:
<head><style type =“text/css”>
p.heading{ font-weight : bold; text-decoration : underline; }
</style>
</head>
This definition defines a heading class that formats text as bold and underlined.

Frames

A framed page is actually made up of multiple HTML pages. There is one HTML document that describes how to break up the single browser window into multiple windowpanes. Each windowpane is filled with an HTML document. Frame Page Architecture § A <FRAMESET> element is placed in the html document before the <BODY> element. The <FRAMESET> describes the amount of screen real estate given to each windowpane by dividing the screen into ROWS or COLS . § The <FRAMESET> will then contain <FRAME> elements, one per division of the browser window. § Note: Because there is no BODY container, FRAMESET pages can't have background images and background colors associated with them. Frame Page Architecture <HTML> <HEAD> <TITLE> Framed Page </TITLE> <FRAMeSET COLS=“23%,77%”> <FRAME SRC=“Doc1.html”> <FRAME SRC=“Doc2.html”> </FRAMeSET > </HEAD> </HTML>
