  10. Markup Language • Method of annotating text in a descriptive way for presentation and/or processing. • Taken from “marking up” a manuscript.

  11. Markup Language Examples • HTML • XML • TeX

  12. HTML Tags • Singleton • A single tag that has no corresponding closing tag • Paired • A tag with a starting a closing tag. The closing tag is denoted by a leading ‘/’

  13. HTML Tags ( Examples ) • Singleton: • <br> • <hr> • <img> • Paired: • <p> Hello World </p> • <strong> Great Class! </strong> • <em> BYE </em>

  14. HTML Validation (HTML 5) <!DOCTTYPE HTML> <html> <head> <meta charset=“utf-8”> <title> Simple Page </title> </head> <body> <p> Hello World </p> </body> </html>

  15. Layout vs Style • Either placed in the html file or a css file. • This books will used HTML 5 • Therefore all pages used strict HTML • For example, center, font and others are not allowed.

  16. Questions! • Word Wrap and White Space • Line Breaks • What is the HT in HTML? • Absolute vs Relative Reference? • What is a URL?

  17. Forms <!DOCTYPE HTML> <html> <head> <meta charset="utf-8"> <title>First Form</title> </head> <body> <form> <p> This is a simple HTML page that has a form in it. <p> Hobby: <input type="text" name="hobby" value=""> <input type="submit" name="confirmButton" value="Confirm"> </form> </body> </html>

  18. Query Strings • A query string is appended to a URL and carries data that is being passed to a web application • It takes the format name=value • The ‘?’ character is used to separate the URL from the query string. It does not form a part of the query string • Pairs are separated with the ‘&’ character • Example: • http://www.forReal.com/test.html?country=USA&State=FL

  19. More about forms and JSP • We will cover the rest of chapter 1 in the video lecture. • The Video lecture for Chapter 1 will be posted either Saturday or Sunday. • I will be posting a Java review as well. • Finished Chapter 1 and read Section 2.1 for next Class • We will have a quiz next week (Chapter 1) plus one Java question (from what we covered today.)
