Don't worry if you don't understand some or even any of this straight away, the web is full of complicated explanations that describe essentially simple process's. It takes a little time but it will all make sense in the end. I've put together a small overview of some of the major components that make up web pages but don't forget if there is anything you don't understand you can always ask.
What is HTML?
HTML (Hypertext Markup Language) is a programming language used on the WWW (World Wide Web) in
order to create web pages. Web browsers than interpret the HTML and display it so that users are able to
view it. HTML is actually a very simple language once the basic concepts are understood. Just remember HTML is a
client-side language which means the data is interpreted locally on your computer, not from the server.
CSS (Cascading Style Sheets) are a set of rules that define how an HTML page is displayed. They are normally stored in Style Sheets (.css). CSS is a breakthrough in Web design because it allows developers to control the
style and layout of multiple Web pages all at once! This will ultimately save you a huge amount of work and it is the way the web is going so this is very important.
