Basic HTML with CSS/FCC: My Tribute Page - How do I start?

Tell us what’s happening:
I am using to do the project but I cant understand how to connect HTML codes with CSS when they are in different windows. I need your help to understand this. I did all the modules but somehow during the project, I get confused how to start and make anything appear. Thank you very much for your help. I appreciate it.

Your code so far

  <script src=""></script>

<!doctype html>
    <title>FCC: My Tribute Page</title>
    <link type="text/CSS" rel="stylesheet" href="style.css" />
<title>FCC: My Tribute Page</title>

.red-text {
  color: red;

<h1 class="red-text">FCC: My Tribute Page</h1>

Challenge: Build a Tribute Page

Link to the challenge:

In Codepen, there are three windows: for HTML, for CSS and for Javascript.
You don’t need to link them. They are linked for you automatically behind the scenes . Simply write HTML in html section, CSS in CSS section. Take note: It is not necessary to include <!doctype html> or
<head> </head> tags in your HTML because they have already been added for you behind the scenes. For example copy and paste the code below in HTML section

<div class = 'testing'>  Testing Testing </div>

then copy and paste the code below in CSS section

          background-color:  gray;

         background-color: yellow;
         color: blue;

then save. You will see the result in the window. As simple as that. Just start coding!
Make sure you have a codepen account before you start doing all of the above.

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.
