Adjust the CSS for .mc-main button.close; changing the position will resolve that. You could also give it padding to make the button more obvious.
It seems to be inside another container as this css made no difference:
.mc-main button.close {
object-position: right top;
}
could you give an example code that will put the close button either at the top right or left of the box?
This seems to be much easier to see:
.mc-main button.close {
left: 8px;
top: 7px;
vertical-align: middle;
outline: none;
}
button.mc-toggle.close:after {
content: ‘Close’;
position: absolute;
top: -3px;
left: 25px;
}
