title: Path to folder outside of folder
body: <p>I have a folder for all my css in my main folder called "main."  In "main" I have another folder called "math." I would like to use my css in the "math" folder, but when I type:</p>
  
  <pre><code>      &lt;link rel="stylesheet" href="css/basic.css" type="text/css" media="screen" /&gt;
  </code></pre>
  
  <p>on the index.html of the "math" folder it doenst work. I think it's because it's looking for the css folder inside of the math folder.  How can i link to the css folder, which is not in the math folder?</p>
