Lesson 6 Jumbotron: Fonts


#1

I don't understand what I'm doing wrong for Lesson 6.
Here are my codes for the two instructions:

 <link href="font.css" rel="stylesheet">
<link href="main.css" rel="stylesheet">
<link href="http://s3.amazonaws.com/codeacademy-content/courses/ltp/css/shift.css" rel="stylesheet">

.jumbotron {
color: #fff;
font-size: 20px;
font-family: 'Shift', sans-serif;
}

can you please post you full code with the error message and objective?
