* Raw html can be embedded

The following will render the tag as is:

#+html: <code> Hello </code>

And this will render some Javascript:

#+html: <script> alert('hello') </script>

** HTML blocks

They behave as follows:

#+begin_html
<p style="color:#cafe12; background-color:#999999">
<pre>

Hello.

</pre>
</p>
#+end_html
