+Like we mentioned, D3 takes advantage of a lot of web standards.

+- [SVG](#svg)
+
+### HTML
+
+HTML (HyperText Markup Language) is a text format that most web pages are
+written in. It's loosely related to the XML family, but much less strict (for
+example some tags such as `<br>` don't need matching closing tags.
+
+The basic outline of an HTML page is something like this:
+
+{% highlight html %}
+<!DOCTYPE html>
+<html>
+  <head>
+    <title>TITLE GOES HERE</title>
+  </head>
+  <body>
+    MAIN CONTENT GOES HERE
+  </body>
+</html>
+{% endhighlight %}
+
+### CSS
+
+CSS (Cascading Stylesheets) is a language for styling web pages.
+
+### The DOM
+
+### SVG
+
 like a whirlwind tour of web standards, these are the hard bits you already understand (or if you don’t, it’s ok! you can pick this stuff up pretty quicky
