Without any script tags, the HTML and CSS work fine. After I add the script and I load the page nothing appears.
<!DOCTYPE html>
<html>
    <head>
        <title>E-Chef: Homepage</title>
        <script type="text/javascript" src="jquery-1.5.2.min.js"/>
        <link rel="stylesheet" type="text/css" href="/Users/stephenhjb/Desktop/Html:Css:JQuery/E-Chef/Stylesheets/E-Chef.css"/>
    </head>
    <body>
        <div class=border>
        <h1 class="header big">E-Chef: All your recipes in one place. Online.</h1>
        </div>
        <script type="text/javascript">
            $(document).ready(function(){ 
            $('div').animate({'fontSize+=36'}, 2000, 'linear');
            });
        </script>
    </body>
</html>
Here is the E-Chef.css file:
.header {
    font-family: Times New Roman;
    color: #5F9EA0;
    text-align: center;
    background-color: #FF7F50;
    border: 30px dotted #FAEBD7;
    margin: 0 0 0 0;
}
.big {
    font-size: 36px;
}
.border {
    border: 5px solid black;
}
