What's the difference between HTML & JavaScript & CSS?

Definition:You use HTML to create the actual content of the page, this means in HTML you define the basic structure and the contents of a website.Example:On the example page HTML is responsible for the text written there, and the structure (there is one header block, one navigation block and many content blocks on the bottom)

Definition:CSS is responsible for the Design of the Webpage, how every thing looks, and where it is on the page.Example:Here is CSS Responsible for the text being in a dark grey, the navigation being orange, the text fields having round edges, and all the other stuff that is designed specificly for the website.

Definition:Javascript is responsible for everything that has to change or get animated after the website loaded, for example you can create a button that makes text disappear when you click on it, you can nearly do anything with javascript, you even can load more data from the server, that you want to appear on the webpage.Example:On this page Javascript is responsible for the appearing of the thumbnails with the stories in the content area and for the sub navigation where you can choose between different categories etc. The stories of the selected category will than be loaded by the javascript.
