Style changes to .video etc for step 3
HW4 Step 4:
This one is a little tricky. First, we create a new 12
column grid within the enclosing span8 and split
it into three span4's. Then we style them in such
a way that the big number is up top in an h3, and
the small descriptor is underneath in a p. Finally,
we use linediv-l and linediv-c in an interesting
way with the media queries, to give vertical lines
when these spans are laid out horizontally (in a
desktop view) and horizontal lines when laid out
vertically (in a mobile view).

HW4 Step 5:
The thermometer is straightforward. We just use
the Bootstrap progress bar:

HW4 Step 6:
The main Preorder button is straightforward; we
use the built in Bootstrap button class. For the
social buttons we need to use bootstrap-socialbuttons and this forces a FontAwesome import
as well (both of which are in the <head>).

Removed remaining styling from initial index.html
HW4 Step 7:
The marketing copy uses the text-align CSS
property to justify the text and the img-polaroid
Bootstrap class to style the images, but is
otherwise fairly straightforward. As with the
content further up the page, the overall content
is structured as two five column spans, each
offset 1 span from the side

HW4 Step 8:
To get the accordion effect for the FAQ, we
introduce a little JS from the Bootstrap
framework. We need to import jquery.js for
bootstrap.js to work, so both of those go in the
<head>. Then we use the built-in code from
Bootstrap to add an accordion:

HW4 Part 9:
Finally, we do a little styling of the footer using
the font color property. We keep it light but just
barely readable, so as not to attract attention.
