HTML
What has this got to do with your MySpace Profile ?
The easy answer is that html is the language of all Myspace profile pages.
What is HTML anyway?
Well, HTML stands for Hyper Text Mark-up Language and is the "secret code" that is used to create the look and layout of all the documents on the web. Why do I call it the secret code? Because everything on this web page is the result hidden instructions, called tags, that tell the web browser how to display the text, the images, the color, and such. Moreover, the web browser doesn't display the tags on the web page…so, that's why I call it the secret code.
It's a programming language used on the WWW (World Wide Web) in order to create web pages and of coruse your Myspace profile page.
Sound confusing? It might help for you to see an example of what HTML looks like with all those tags.
