Reposting this question because the first two tries ended up in 404 errors.

1) I’m trying to fix the home slider on the home page of http://dekalbdems.com. I found some images which fit 1700×900, but in mobile view or in a smaller browser window, the images in the slider break from the bottom and show the gray underneath. I identified the culprit as the media query for when the window if 768px or less, but I don’t know where I can disable that so that the images fill the entire slider space. I want the slider images to adjust like on http://fultondems.org ‘s home page slider.

2) I’m trying to find where I can change the style which places a break underneath each of those four buttons under the slider. In CSS I saw that the space underneath each button is under .vc_btn3-container {
margin-bottom: 21.73913043px;
}

Where is this margin-bottom set where I can remove that space? It shows up as gaps between the color buttons on mobile.
