Make CSS Styles Work

Hey Maya -

Big apologies.  It turns out that bootstrap just updated their code and it required a small change in our guide to follow along.  The problem was when we installed bootstrap the bootstrap page on github has the incorrect instructions.  I'm going to adjust the lessons now to fix that problem - you didn't do anything wrong.

Thank you for bringing this to my attention.

As a side note, this is a GitHub pull request.  This is how I can show you code that I think you should add to your project.  It allows you to look at the code, you'll see the green code is code that's added and the red is code that's deleted.  The "Files changed" tab will show you the code.

"Commits" will show you a listing of the individual commits I'm trying to send you.  And this tab, the conversation tab you can use to communicate about the change.

If you want to suck in all this code into your project you can by pressing the green merge button.  After you press the merge button, you'll have to update your web dev environment to have the latest updates from GitHub and to do that you can run this command:

```
git pull origin master
```

Hope this helps.

Aloha,
Ken
