Awesome, much appreciated!
I think I found what is happening. When width gets to 576 the @media query launches for “body.modal-cacsp-open .modal-cacsp-position>.modal-cacsp-box-close” changing the postition to absolute. If I comment out the below bit of code it works.
> .modal-cacsp-box-close {
color: $white;
text-decoration: none;
position: fixed;
right: 0;
top: 0;
margin: 15px;
/* @include responsive(width-max-small-down) {
margin: 0;
position: absolute;
margin-top: -5px;
} */
padding: 0 8px;
font-size: 2em;
