This document provides an introduction to HTML and creating basic HTML files. It explains how to create a simple HTML file using Notepad or TextEdit, save it with an .html file extension, and open it in a web browser. It notes that web browsers like Chrome are used to open .html files, similar to how other programs open different file types. Finally, it discusses how there are many browsers that all function to display HTML files, but may differ in speed, appearance, or other qualities.

3. Recap from last time (I)
• HTML is very important because it‟s used in all websites
• Along with CSS and jQuery/Javascript, HTML is one of the building
blocks of the internet
3
HTML as the
structure/skeleton
CSS as the
presentation/clothing
jQuery/Javascript as
the action/movement

Recap from last time (II)
• When we navigate to a website, our request is transmitted to a
server which sends us the files to load the page
• Any local changes we make can be seen on our computer only

5. Let’s try creating our own HTML file
• We‟ve already seen lots of websites created with HTML
• It‟s easy to do ourselves!
5
Remember this?

6. Our first HTML file (I)
1. If using a PC, open the Notepad application. If on a Mac, open
TextEdit
2. Type “I am master of the internet!”

7. Our first HTML file (II)
3. Save the file by going to „File‟„Save As…‟ (PC) or „File‟„Save‟
(Mac)

MacPC

8. Our first HTML file (III)
4. If using a PC, delete “.txt” and rename it to “.html”. If on a
Mac, change the „File Format‟ to „Web Page (.html)‟

MacPC

9. Our first HTML file (IV)
5. Name the file “my-first-page” (don‟t forget where you saved it!) and
hit „Save‟.

10. Our first HTML file (V)
6. Let‟s see what our file looks like in our browser. Open up your
Chrome browser. If using a PC, press the Ctrl key and then press
the “O” key (as in Orange). If on a Mac, go to „FileOpen File‟.

11. Our first HTML file (VI)
7. Now locate the file, select it, and click „Open‟

12. Our first HTML file (VII)
8. There we go!
12
This address may look different for you

13. Something looks different…
• If you look at the address in the bar (known as a URI, or Uniform
Resource Identifier), you‟ll see it looks different from most websites
you are familiar with
13

14. HTTP vs. File
14
Most website URIs
look like this:
or like this, for short:
Addresses for files on your
computer look like this:
• HTTP stands for HyperText
Transfer Protocol
• This basically tells your
computer to find this address
on the internet
• File tells your computer to look for
this address on your local computer

15. What exactly is a web browser?
• A web browser is an application used to access and display web
pages and other content on the internet
• In the same way that Microsoft Word is used to open a .doc file and
Adobe is used to open a .pdf file, a browser is used to open a .html
file
15
opens
.doc files
opens
.pdf files
opens
.html files

16. Why are there so many different browsers? (I)
• So far, we have been using our Chrome browser, but there are many
different web browsers to choose from:
16
Chrome Internet
Explorer
Firefox
Safari Opera

17. Why are there so many different browsers? (II)
• There are different browsers for the same reason there are so many
different brands of cars
17
Ford Vauxhall Land Rover
Ferrari Hummer

18. Why are there so many different browsers? (III)
• Like with cars, the basic function of all browsers is the same – to
take the HTML code a server sends us and make it appear on our
screen
• Each browser does things a little differently:
• Some are faster
• Some look cooler
• Some are easier-to-use
• Some have just been around for as long as anyone can remember
18

19. Summary (I)
• It‟s simple to create an HTML file – no different from creating a Word
document or a PDF file
• .html files are opened with web browsers, in the same way that .doc
files are opened with Microsoft Word and .pdf files are opened with
Adobe Reader
19
opens
.doc files
opens
.pdf files
opens
.html files

20. Summary (II)
• A web browser is an application used to access and display web
pages and other content on the internet
• There are many different browsers, but they all have the same basic
function – to load HTML files
20
Chrome Internet
Explorer
Firefox Safari Opera
