Recap from last time (I)
• Learning to read code well is important – we will spend more time reading other people’s code than writing code ourselves
• Remember the DRY Principle: Don’t Repeat Yourself. Reuse code whenever possible!
• Using open source code that has been shared on the internet can help us save a lot of time

Recap from last time (II)
• Websites such as Wordpress provide many prewritten templates of code to choose from
• Twitter Bootstrap is an example of a free framework that gives us a helpful toolkit for styling our website
• Frameworks like Bootstrap can transform our website without us writing a single line of code!
5
Remember how the internet works?
• When we visit a website, we rely on servers to send us the files for the page. So to change what everyone sees, we need to change the files on the server itself.
HAHAHA
RouterISP
Facebook server
Amazon server
Youtube server
DNS
We use FTP to make our website public (I)

1. File Transfer Protocol (FTP) is what we use to share files between computers through the internet
Host server

2. We use FTP to upload our files to a host server, which is a server connected to the internet

4. When someone visits our page, the server sends them our page’s files and they can access our website!

HAHAHA
But before we can launch a website, we need to do two things (I)
10
1. Pay a one-time fee to buy a domain name
• A domain name is an address for people to find you on the web, like www.codecademy.com or www.theguardian.com
• Domain names can be purchased from many different websites, but the price depends on how popular your name is
• For example, www.books.com will cost much more than www.nobodywillfindme.org
But before we can launch a website, we need to do two things (II)

2. Pay a hosting company to store your files on their servers
• Hosting companies usually charge a monthly fee to continually store all your files
• The more you need to store, the more you will have to pay
12
Codecademy has a free alternative to launch your website
• We can easily launch our code and see what it looks like through Codecademy’s “Launch Your Website” course
• It’s faster than having to purchase a domain name and pay a hosting company, and best of all, it’s absolutely free!

Launch Your Website (III)
3. Back in our browser, paste the copied code into the “index.html” tab. You should immediately see the results of the HTML appear in the white box!
We can preview what our HTML
would look like in the browser

Launch Your Website (IV)
4. Now it’s time to upload our CSS. Open up our “smelly-cat.css” file and copy all the text.

Click this tab

Launch Your Website (VI)
6. Even though we pasted in our CSS code, it doesn’t look like it had any effect on our page. Can you figure out why?
Here’s what our HTML would
look like in the browser

Launch Your Website (VII)
7. To see the error, we need to go back to our HTML code. Click the “index.html” tab. Notice that our HTML file is still linking to “smelly-cat.css”!
First click this tab Linked to the
wrong CSS file
20
Launch Your Website (VIII)
8. To fix the error, we need to link to the correct CSS stylesheet. Replace “smelly-cat.css” with “style.css”.
Stylesheet named “style.css”
Fixed link – now linked to
“style.css”

Launch Your Website (IX)
9. The preview box now shows the results of our CSS styling!
There’s our webpage!

Summary (II)
• Launching a website costs money
• We need to pay a one-time fee to purchase a domain name
• We need to pay a monthly fee to a hosting company for storing our files on their servers
• We can also do it on Codecademy for free!
