DNS – Domain Name System
• The DNS server follows a series of
steps to turn the human readable web
address into a machine-readable IP
address (69.127.23.407) if not stored in
your cache
IP – Internet Protocol
• An IP address (69.127.23.407) is the
equivalent of your home mailing
address, not so easily to remember
• Web browsers translates the basic
HTML (Hypertext Mark Up Language)
code that allows us to see images, text
videos and listen to audio on websites,
along with hyperlinks that let us travel
to different web pages

3. WEEK 2 REVIEW
HTTP: HyperText Transfer Protocol
• A Protocol is a set of instructions, or
commands
• Entering a domain name (URL) in
your web browser sends out a HTTP
command to the web server (ISP)
directing it to fetch and transmit the
requested Web page
URL: Uniform Resource Locator
• A URL is used to identify a network
resource on the Internet
• Network resources are files that can
be web pages, text documents,
graphics, or programs
• A URL is to a web site, as your street
address is to your home

4. RESPONSIVE DESIGN

5. WEEK 2 REVIEW
Protocol: The how
• How your browser needs to communicate with the web server when sending or
requesting files
Domain: The where
• The unique reference that identifies a web site on the internet (e.g. google.com)
Path: The what
• A file or directory on a web server

WHAT IS
HTML?

7. GOAL FOR TODAY:
By the end of today’s class I want you to find this tattoo funny…

8. WHAT IS HTML?
HTML stands for Hypertext Markup Language
• HTML is the publishing language of the World Wide Web
• It’s not a programming language but rather a way of describing something
• It is not complicated
• It is easy to write and very easy to understand
• Most HTML tags are self explanatory as they describe themselves with the tag
they use making them easy to remember and understand
• It is the web browser that interprets the HTML to display the site content

9. SOFTWARE
• You do not require any special software to write HTML, it can be done in Text Edit
(Mac) or Notepad (PC)
• In this course we will be using Dreamweaver.

10. TAGS
• All HTML code reads like a story, it has a beginning, middle and end
• The story must be complete in order for it to work

11. TAGS
• Tags are the parts of any HTML documents
• All tags describe a piece of the website content
• Tags do not appear in the web browser – but you can see them by “viewing the
source”

12. STEP 1: PLANNING
• Open up a web page such as apple.com
• Right click somewhere on the page – around the top left works – and select “view
source”

14. STEP 1: PLANNING
• Look through the code – you’ll see a combinations of “tags” such as:
• <li> … text then </li>
• <div> … text then </div>
• <a …> … text then </a>

15. TAGS
• It is good practice to right all of your HTML code in lower case although it is not
required, for this class all code must be lowercase
• Example: <p>This is a paragraph</p>

16. TAGS
• MOST tags require an OPENING and a CLOSING tag

17. TAGS
• If you forget to end a tag it effects the whole story
• We need to show when an element such as a heading starts and finishes
• Good: <h1>This is a heading</h1>
• Bad: <h1>This is a heading
<p>This is a paragraph</p>

18. OPENING TAGS
• Opening tags look like this…

19. CLOSING TAGS
• Closing tags look like this…
• The closing tags have a forward slash ( / ) before the characters, indicating that the
item being described is finished

20. SELF-CLOSING TAGS
• Some tags, known as “self closing” or “self terminating” do not require a closing tag
• Example: <img /> <br /> <hr /> (the / at the end recommended)
• An easy way to remember these tags (self closing) is that they are just one thing
• An image is just an image, where as a paragraph is a bunch of words
