Recap from last time (I)
• CSS is just as important as HTML because it allows us to style a
page to make it look pretty
• Changing the CSS of a site can make a big difference!
3

Recap from last time (II)
• It‟s just as easy to edit CSS as it is to revise HTML
• A server actually sends TWO files when you request a webpage –
HTML and CSS
• You need both to see the full version of the website

Let’s write our own CSS file (I)
1. Creating our own CSS file is the same process that we looked at in
Lesson 2 for creating an HTML file. If using a PC, open Notepad. If
using a Mac, open TextEdit.

Let’s write our own CSS file (II)
2. Type the following code (make sure to copy it exactly!)
6
body {
background-color: #FFFFF0;
color: #FF0000;
font-family: copperplate;
text-align: center;
padding-top: 50px;
}

Let’s write our own CSS file (III)
3. Go to „File‟‟Save‟ and save the file as „smelly-cat.css‟.

Let’s write our own CSS file (IV)
4. Now open your Chrome browser and go to „File‟‟Open File‟.
Locate our CSS file and open it.

Let’s write our own CSS file (V)
5. That‟s weird…it looks the same as the text we entered. I thought
CSS was supposed to look cool!

Let’s write our own CSS file (VI)
6. Well, remember that you can‟t style a webpage using CSS if it
doesn‟t have an HTML foundation. So now we need to create an
HTML file to pair with our CSS file. Let‟s open up a new file in
Notepad (PC) or TextEdit (Mac).

Let’s write our own CSS file (VII)
7. Type the following code (make sure there aren‟t any typos!)
11
<html>
<head>
</head>
<body>
<h1>Smelly Cat</h1>
<h3>By Phoebe Buffay</h3>
<p>
Smelly Cat, Smelly Cat,<br>
What are they feeding you?<br>
Smelly Cat, Smelly Cat,<br>
It's not your fault.<br>
</p>
</body>
</html>

Let’s write our own CSS file (VIII)
8. Go to „File‟„Save‟ and save this file as „smelly-cat.html‟.
12
MacPC

Let’s write our own CSS file (IX)
9. Open up your Chrome browser again. Go to „File‟„Open
File‟, locate „smelly-cat.html‟ and open it.
13
MacPC

Let’s write our own CSS file (X)
10. You can see that the content appears, but it hasn‟t been stylized at
all. This is because our browser doesn‟t know that the HTML file
and CSS files should be linked together. Let‟s link them and see
what happens…
14
MacPC
This address will look different

Let’s write our own CSS file (XI)
11. Going back to „smelly-cat.html‟, add the following line of code
between the <head> tags. It should now look like this:
15
<html>
<head>
<link rel=“stylesheet” type=“text/css” href=“smelly-cat.css”>
</head>
<body>
…
This line tells the browser to look for a
CSS file called “smelly-cat.css”

Let’s write our own CSS file (XII)
12. Save “smelly-cat.html” and open it again in the browser. Notice
anything different?

CSS lets us style a page how we want (I)
• Let‟s see how just a few lines of CSS code were able to transform
the look of our page
17

CSS lets us style a page how we want (II)
18
body {
color: #FF0000;
text-align: center;
padding-top: 50px;
}
1

• This sets the background color to „#FFFFF0‟, which is shorthand for
pale yellow
• This sets the font color to „#FF0000‟, which is shorthand for red
• This changes the font style to one named „Copperplate‟

the page

Be creative and use your imagination!
20
• There are so many possible ways to style a website – you‟re limited
only by your imagination!

Summary (I)
• Creating a CSS file is just as easy as making an HTML file
• CSS always needs to be paired with HTML for the styling to take
effect
21

Summary (II)
• The HTML code must tell the browser where to find the matching
CSS file
• There are infinite possibilities in styling a website!
22
