Height of color section not responding to CSS

I have looked at a few prior posts and tried the suggestion to no avail.
I would like to havet he whole image in this particular color section to show. For sopme reason it is not responding to the height commands in CSS.

#education{
height: 1200px !important;
font-size:15px;
}

I have tried min-height and max-height as well with no luck.
The actual image in the color section is 1600 by 1067 and is set to parallax and to stretch to fit with no padding.

The link is http://bit.ly/1flsidi and the color section in question is the one with a question mark image.

I have tried the below:

.avia-section {
min-height: 1400px;
}
