So I am pretty new to html and css, and I'm am trying to do a simple id using div, but when I do something in the css file nothing changes.
HTML
<!doctype html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="main.css"/>
</head>
<body>
<div id="Page-Container">
Hello world
</div>
</body>
</html>
CSS
#page-container {
background: red;
}
The Text still comes out with no red background.
