  16. 16. List Unordered list -Code: <ul> <li>Coffee</li> <li>Milk</li> </ul> -Output:  Coffee  Milk  Ordered list -Code: <ol> <li>Coffee</li> <li>Milk</li> </ol> -Output: 1. Coffee 2. Milk
  17. 17. Table <table border=“1"> <tr> <th>Heading</th> <th>Another Heading</th> </tr> <tr> <td>row 1, cell 1</td> <td>row 1, cell 2</td> </tr> <tr> <td>row 2, cell 1</td> <td></td> </tr> </table> Heading Another Heading Row 1, cell 1 Row 1, cell 2 Row 2, cell 1
  18. 18. Create Links  A Hypertext link  < a href=“http://www.”>apj Home</a>  Output: APJ Home  A Email link  <a href=“”> Email me</a>  Output: Email me

  25. 25. Sample page of Code <html> <head><title>First Page</title></head> <body> Hello! This is my first page of code. I can't believe I'm on my way to being a webmaster. This is so great!!! </body> </html>
  26. 26. What does that look like?
  27. 27. DHTML  Dynamic HTML.  Just as access is dynamic database environment.  Can have control that respond to events.  Can have control code module.  Can be written in VB(script)
  28. 28. INTERNRT EXPLORAL DHTML  Developing for two DHTML environment takes three time the developing time.  IE support active Xcontrol .  IE support VB script.  80% of the world browsing activity is done with IE.
  29. 29. ADVANTAGE OF DHTML  Centralized code for distribution.  Can be secure by using https.  Richer event model higher control are display.  Small foot print  Can monitor usage easier.
  30. 30. DISADVANTAGE.  Use script language that mean:- -All variable are variants. -Error handling is limited. • Debugging can be awkward.
  31. 31. FEATURE  Data binding.  Behaviors or script.  Support for XML.  flexible object.
  32. 32. JAVASCRIPT :-  JavaScript is programming language designed for webpage's .protocols used by the JavaScript is “http://”  Developed by :Netscape. In 1995  Purpose: to Create Dynamic websites.  Widely Used (web designing).
  33. 33. Why Use JavaScript  JavaScript enhances Web pages with dynamic and interactive features.  JavaScript runs in client software.
  34. 34. What Can JavaScript Do?  Common JavaScript tasks can replace server-side scripting.  JavaScript enables shopping carts, form validation, calculations, special graphic and text effects, image swapping, image mapping, clocks, and more.

  36. 36. Example Of JavaScript <html> <head> <SCRIPT language = java script> Var name=prompt(“RAMGOPAL”); </SCRIPT> </head> <body> <SCRIPT language =“java script”> Document .write(“<H2>hello RAMGOPAL</H2>) </script> </body> </html>
  37. 37. ADVANTAGE OF JAVASCRIPT  Interpreted language.  Embedded with HTML.  Minimal syntax- easy to use.  Quick development.  Designed for simple and small program.  Easy Debugging and testing.
