.wpcw_fe_unit_progress_complete span{
background-image:url('http://wpcw4092.dev/wp-content/uploads/2017/10/check-mark.png'); /* changes background image to different image /*
background-size: 24px 24px; /* sets background image size, however, this is not necessary if the image is created at 24x24 pixels. It is recommended to make image to size to reduce load time*/
