Working on a project and I currently have this:
<!DOCTYPE html>
<html>
<head>
<title>Jams</title>
<link rel="stylesheet" type="text/css" href="http://fonts.googleapis.com/css?family=Open+Sans:400,800,600,700,300">
<link rel="stylesheet" type="text/css" href="http://code.ionicframework.com/ionicons/2.0.1/css/ionicons.min.css">
<link rel="stylesheet" type="text/css" href="styles/normalize.css/normalize.css">
<link rel="stylesheet" type="text/css" href="styles/main.css">
</head>
My directory is
jams
|---- musicplayer[index.html]
|---- styles
| |---- main.css
| |---- normalize.css(folder)
| | |---- normalize.css(file)
Sorry if the directory might seem confusing but it mainly states that jams is the parent folder and the rest of the folder are inside, with the brackets being the files inside the folders. The only exception is normalize.css where that's a folder inside of styles, and inside of the normalize.css folder is a normalize.css file.

/meaning relative to the website root?
