You should do the following

  1. set the size of each slider image to “contain” in the backgrounds section and turn off “tile”
  2. set the slider size to 100% width
  3. set the width of the “Illus Div Block” to 78% (or whatever size you want - but you have to set it)
    4.go to edit grid and set the column width to 100%

this should do it for you

Woohoo! Thank you so much! I wanted to keep the images covered instead of contained, but I applied your steps from 2-4 and it worked amazingly!!!
