Issue 1:
I`ve noticed that ditch-custom-css-for-bootstrap challenge has a small bug.

Text in "danger button" is not in center. I reboot the page and my browser, but it does not help.

Goole Chrome 48.0.2564.116 m, Windows 7 x64.

(Is there any command to write info about browser and OS? I use search, but can not find.)

My Code:

<link href="http://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
<style>
.red-text {
color: red;
}

h2 {
font-family: Lobster, Monospace;
}

p {
font-size: 16px;
font-family: Monospace;
}

.thick-green-border {
border-color: green;
border-width: 10px;
border-style: solid;
border-radius: 50%;
}

.smaller-image {
width: 100px;
}
</style>

<div class="container-fluid">
<h2 class="red-text text-center">CatPhotoApp</h2>

<p>Click here for <a href="#">cat photos</a>.</p>

Issue 2:
Hmm, I don't know why, but I am getting issues with the preview layout in the bootstrap section.

First in the buttons section : http://prntscr.com/89uesz

Then in the check box section: http://prntscr.com/89ujcq

I am sure there is no error with my code, but still I am pasting the code for it here
