HTML in 10 Steps or Less- P23:p Welcome to HTML in 10 Simple Steps or Less. Our mission in writing this book is to provide a quick and accessible way for you to learn Hypertext Markup Language — the lingua franca of the World Wide Web. We hope this book provides a resource that beginning and intermediate HTML coders can use to improve their Web development skills. It is also our hope that it fills multiple roles as both a teaching tool and a reference once you expand your skills.

  1. 416 Part 15 Task 194 Creating Lists Lists come in three varieties: ordered lists (also called numbered lists), unordered lists (bulleted lists), and definition lists. 1. Select your list — any series of lines of text or paragraphs. 2. To create a bulleted list, click the Unordered List button. notes • There’s a difference between unordered and 3. To create a numbered list, click the Ordered List button. Figure 194-1 shows an unordered list created from four lines of text. ordered lists. If you give instructions, such as dri- ving directions, use an ordered list so that readers know how to perform the tasks in sequence. If your list has no order or priority implied, use an unordered list. • When you build a definition list, every other line is des- ignated as either a term or definition. Definitions are indented automatically to link them clearly to the terms above them. • If you insert a new line at the end of an unordered or ordered list, you’ll get one more bulleted or numbered line. Press Enter twice to exit list mode. Figure 194-1: An unordered list implies a series of equally-important items with no implied priority between them. 4. Delete items in your list and observe the changes in the list itself. If your list is numbered, the number sequence updates automatically. 5. Add items to your list and observe the changes to the number of bul- leted items or the number sequence of list items. 6. To create a definition list, select the text and choose Text ➪ List ➪ Definition List. As shown in Figure 194-2, the items in the list alternate between being terms and definitions.

  3. 418 Part 15 Task 195 Proofing Page Text D reamweaver’s spell-check feature works very much like that in any word processor. Words not found in the internal dictionary are listed as misspelled, and you have the opportunity to choose an alternate spelling or edit the text directly. 1. To spell-check just one part of your page, select the text and choose Text ➪ Check Spelling. If you want to check the entire page, just choose the command without first selecting any text. 2. In the Check Spelling dialog box (see Figure 195-1), each misspelled word appears, one by one. Edit text here Spelling suggestions list Figure 195-1: Mistakes found within the selected text or on a page appear in the Word Not Found in Dictionary text box. 3. Select an alternate spelling from the Suggestions list or type a correc- tion in the Change To text box. 4. Click Change or Change All if you want to implement the change. caution • Use care when clicking the Add to Personal button. If you aren’t absolutely sure the word is spelled cor- rectly, verify it before adding it to the personal dictionary. Otherwise, your misspelling won’t be flagged the next time you make the same mistake. Please purchase PDF Split-Merge on to remove this watermark.

In the Find In list box choose the scope of the Find and Replace ses- sion: Current Document, Entire Current Local Site, Selected Files in Site, or Folder. 4. In the Search For list box specify if you want to look for anything other than text. Your choices include Source Code and Specific Tag. 5. Type the text you’re looking for in the text box to the right of the Search For list box. 6. Type what you want the found content to be replaced with in the Replace With text box. caution • Use care when typing your Search For and Replace With text. If spaces, special characters, and capitaliza- tion don’t match perfectly, no replacements will be made. Please purchase PDF Split-Merge on to remove this watermark.

Figure 196-2: Results of performing a requested Find and Replace • If you first select text before choosing Edit ➪ Find and Replace, that selected text will appear in the Search For field. That’s especially handy for specific text phrases that repeat across the site. In Code view, that feature is great for replac- ing long code strings (or HTML tags) with something else. • The options Match Case, Ignore Whitespace Differences (selected by default), and Use Regular Expressions control what searched text meets the Find criteria and therefore what’s replaced with the Replace With text. Your situ- ation and Web page or site content will dictate which options you need. cross-reference • TextPad offers a handy Find and Replace tool, too. Read more about it in Part 12.

  9. 424 Part 15 Task 198 Importing Data Tables from Other Applications S uppose you need to take a Microsoft Excel worksheet or a table from a Microsoft Word document — or even a data table from Microsoft Access or another database management system — and import it into a Web page. This notes task requires importing the tabular data — located in a table, one piece of data • Your tabular data must be in a format that per cell — and inserting it so it’s legible and accessible within Dreamweaver. You can easily make that tabular data appear in a Dreamweaver-created table using Dreamweaver understands. the Import Tabular Data command. The most common format is tab- or comma-delimited text. In an Excel worksheet, 1.

(You can’t use multisheet text files.) This format satisfies Dreamweaver and keeps the original worksheet intact. • Tab delimiters are good if your data comes from a Word table, Excel work- sheet, or Access table after the files have been saved as text files. Figure 198-1: Choosing the source of the tabular data and informing Dreamweaver how you want to use and display it 2. Click the Browse button to select your tabular data file. This opens the Open dialog box (see Figure 198-2). caution • Numeric data is very hard to read.
