9. HTML : An Outline Stands for Hyper Text Markup Language. Not a programming language, it is a markup language. A markup language is a set of markup tags. Markup tags are used to describe web pages. 3
10. TAGS Keywords surrounded by angle brackets < > like <html> They come in pairs like <b> and </b> Common tags are :- <html> <head> <div> <body> <a> <p> <h1> 4
12. Document Object Model Cross platform, language independent model Represents and interacts with objects in HTML documents 6
13. Why HTML5 ? HTML4 hasn’t been updated for about 10 years. XHTML was introduced but it made things stricter and not easier. Embedding audio/video was dependent on flash etc. New websites have to be interactive. 7
14. HTML4 - drawbacks It does not adequately support web applications. Complex structuring of web pages. Complex DTDs Need plug-ins to embed audio and video. Does not support drag and drop features, editing, drawing, error handling etc 8
40. <video> Embed video in web pages Does not require 3rd party plug-ins like Apple QuickTime or Adobe Flash Player. No detection script required Attributes like src, autoplay, loop etc JS to fall back to plug-ins if browser does not support <video> 19
43. <audio> sound or audio stream attributes like src, auto buffer, loop, controls etc audio = new audio( [ url ] ) creates an audio element ,assigns arc=url 22
As many conceive it, its not a programming language. It’s a markup language. *Slidecontecnt* I’m coming to tags. Its on the next slide.
Common tags you’ll find in an html source code are And <p>,<h1> etc<head> includes the external files which u may include in ur html doc such as a css or a javascript file<div> divides the page into sections upon ur need<body> defines the main body of ur division, it consists of several sub tags such as <a> <p> etc etcI think that’s all the basics you need to know to understand further.
The most reason version html4, has been on for over a decade now. And, it hasn't really seen a major update. Sure there's XHTML, but that did little more than make things slightly stricter - making you write better quality code if you were at all concerned with compliance. The main area that was not been addressed yet was web application. To give authors more flexibility and enable more interactive websites, html5 was introduced.Critics say that html5 could actually kill flash and silverlight.
