I need someone to modify my css to make my search box responsive so that it stays confined within the area it's supposed to be in.  Right now, when the other elements expand, the search box is dropped below the nav bar where it is supposed to stay.

This should be an easy fix for someone with the right skills.  I hired someone else to make the changes, but he couldn't get it exactly right.

Please see this video to see the issue in action:

It's slightly different now since the last person made changes, but the goal is the same.

I NEED THIS DONE AS SOON AS POSSIBLE, SO DO NOT RESPOND UNLESS YOU CAN WORK RIGHT AWAY.

Thanks!
