I am very new to coding, but have the basics down for the most part. I recently downloaded Atom and created very simple HTML and CSS files. I used the standard link method (as shown in the code), but cannot seem to get my css to link. My only install thus far has been webBoxio/atom-html-preview.

**HTML:**

```
<!DOCTYPE HTML>
<HTML>
 <body>
     <link rel="stylesheet" type="text/css" href="mine.css">
         <h1>test</h1>
         <p>test</p>
   </body>
</HTML>

```

**CSS:**

```
h1, p {
    font-family: Sans-Serif ;
}

```
