 HTML+CSS Tutorial
 =================
 
-###Who
+### Who
 
 I'm Cassidy.  I'm software engineer & developer evangelist at [Clarifai](http://clarifai.com), and I've been teaching myself HTML, CSS, and other web programming and scripting for over 10 years.
 And I want to teach you now.
 Because you're good looking.
 And because it's useful.
 
-###What

 In this tutorial, we'll start from the very beginning.  You don't need to know anything about HTML and CSS or anything about code to start.  I'll include some tutorial files for you to play with and check out.

 Because this stuff is important.  Whether you're a business person formatting your emails, an aspiring web designer wanting to get your feet wet, or just someone who is interested and hasn't tried any sort of coding, scripting, or programming before, **HTML and CSS are an essential part** of your learning curve.

And because I'm assuming you don't know JavaScript, don't use this unless you're changing this to Arial.  At least not yet. :)
