2. Difference Between Internet and Web
Many people think Internet and Web are the same thing, but they are different:
| Internet | World Wide Web (WWW) |
|---|---|
| It is the big network that connects all computers in the world | It is websites and web pages that we see on browsers |
| Started in 1960s | Started in 1989 by Tim Berners-Lee |
| Uses TCP/IP to work | Uses HTTP to work |
| Has email, games, file sharing | Has websites, web pages, blogs |
| It is like the road system | It is like the cars that use the roads |
Simple explanation: Internet is like electricity, and Web is like your TV that uses electricity.

3 Ways to use CSS:
1. Inline CSS (inside HTML tag):
2. Internal CSS (in the head section):
p { color: red; }
</style>
3. External CSS (separate file):
CSS Selectors:
- Element: p { color: red; } - changes all paragraphs
- Class: .myclass { color: blue; } - changes elements with class="myclass"
- ID: #myid { color: green; } - changes element with id="myid"
