What is HTML? HTML is a language that is read by Internet browsers. It tells how browsers display the webpage. HTML files must have the .html extension, although very old pages do use the .htm extension. HTML stands for HyperText Markup Language. You are probably using Internet Explorer right now.

To view the HTML for this page that you are reading, follow these steps:

• In Mozilla / Firefox / SeaMonkey / Netscape: Press CTRL + U.
• In Opera: Press CTRL + F3
• In Internet Explorer/Avant Browser/Maxthon: Click View. Click Source.

What is XHTML? XHTML is a more stricter and cleaner version of HTML. In the future, XHTML will replace HTML. XHTML stands for eXtensible HyperText Markup Language. IF you learnt HTML before, converting to XHTML might be a tad difficult but shouldn't be too hard.

Remember to read carefully on the lessons and to do each step and apply your skills. Practise makes perfect!
