How to expand background image to full?

I am trying span to full width while testing background img on various screens by making adjustments to style.css. I have performed many searches with little luck. Here is what I have currently for the element which should help explain… Any thoughts?

/*Image for Construction Monitoring*/
.page-id-735 .enigma_header_breadcrum_title {
height: 200px;
background-size:150%;
background: url(“https://beyondmapping.com/wp-content/uploads/2015/07/Construction-Monitoring.png”) no-repeat center center;
}
