title: Starting with a forward slash in html for "href"
body: <p>I started learning html recently, and one thing that really confused me is why do some links have a forward-slash("/") before the path and some links don't?</p>
  
  <p>ie.</p>
  
  <pre><code>&lt;link href="/favicon.png" rel="icon"&gt;
  &lt;link href="/stylesheets/screen.css" media="screen, projection" rel="stylesheet" type="text/css"&gt;
  </code></pre>
  
  <p>vs.</p>
  
  <pre><code>&lt;dt&gt;&lt;a href="reset/index.html"&gt;Reset CSS&lt;/a&gt;&lt;/dt&gt;
  </code></pre>
  
  <p>Is one a relative path and one an absolute path?  and how do href's work exactly? does it just stick on the path name after the base url?</p>
