6. Using Nvu to set up and edit your website

7. Goals of the tutorial Goals of the tutorial: The goals of this are centered around creating interesting, attractive, and compelling web documents in an efficient and productive manner. To learn the Nvu web editor an editor that makes creating web pages only slightly more difficult than creating word processing documents. To learn how to design tables and to use the table tags to create attractive two dimensional layouts. To learn how to find and create a web resource page to keep track of sites that contain free and shareware resources to make creating more attractive web pages easier.

8. WYSIWYG editor Writing Web Pages using the Nvu Web Editor. Nvu works like a What You See Is What You Get (WYSIWYG) word processor, e.g. MS Word.. In the previous lab we actually used some of the HTML tags and created HTML documents. To use Nvu one only needs to: –select the appropriate button in the composition toolbar, –answer the questions in the resulting dialog box and fill in the appropriate text boxes, and –click the [Apply] button to see what the change looks like and the [Close].

9. WYSIWYG editor (more) As we move into the era of dynamic documents, this becomes harder and harder to do. In newer Web page editors, much of the action is also buried in the source code. Thus, it is hidden from the viewer. As a result, Nvu and other similar editors use tags to indicate how the content behaves at the source code level. This hidden layer could include: Java applets, Javascript and other scripts, Forms, Frames, and XML.

25. Composition bar The one button tools are the most frequently used editing operations, and offer assistance with the more complex HTML tags for creating links, targets, images, horizontal rules, and, most importantly, setting up tables. Dialog boxes request user preferences and other information necessary to create the containers for the tag(s). The most common examples are the image and the table tags. Table tags are really containers within containers that denote colors or backgrounds, captions, horizontal and vertical alignment of text and table, and the borders of the table and each cell. Thus, the dialog box involves specifying many items.

Clickable images that link the image to a URL are called buttons. A button can link to another location on the page, another external page, or a sound or video. An image used as a background upon which the text and inline images are placed is called, naturally, a background image. An image with defined clickable regions that point to URLs, or cause an action when a mouse event occurs (onMouseOver, onMouseOut) is called an image map.

Finally, paste it in the "Link to" window. The URL can be a file in the current system's directory, (i.e. a relative URL).

After the link's text and URL are completed and click [OK].

62. Physical Text

63. Lists Simple lists breaks down into two main types: –Unordered lists with each item denoted by a printer's bullet or other symbol, orUnordered –Ordered lists (those that use a number or letter)Ordered Other list types that require the use of the Format button on the tool bar are: –Definition, andDefinition –DictionaryDictionary –MenuMenu Note that the Unordered List will select the style of the bullet (disk) for you based on rules of nesting or indentation. Similarly, for Ordered Lists, it will select order element type (numbers or alphabetic characters). If this offends your sense of layout, use the HTML editor to override Nvu's selection. You can achieve almost all the control needed for any list layout -- select the [Format] button/Character Properties/Paragraph, then select the correct options to determine list style, type of character or disc to display, and the starting value. This is tedious, but necessary for greater control over the details.
