	/* Center and scale the image nicely */
	background-position: center center;

	background-repeat: no-repeat;
	background-size: cover;

	margin-bottom: 0;
}

#survey-form {

	margin-bottom: 20px;
}

.form-control input[type="checkbox"] {
	display: inline-block;
	width: auto;
}

.form-control label {
	display: block; /* acts like a <p> tag takes up a new line and entire width */
	margin-bottom: 7px;
}

.form-control input,
.form-control select,
.form-control textarea {
	font-family: inherit;
	border: 1px solid #777;
	border-radius: 2px;
	padding: 7px;
	display: block;
	width: 100%;
}

* {
	box-sizing: border-box; /* ensures the input boxe are inside the form container */
}

	padding: 10px;
	font-family: inherit;
	width: 100px;
