Delay of the closing cross

If you want to delay the closing cross by a few seconds and make the user pay attention, just add a simple code to the CSS styles.

Insert this code into the CSS:

ml-close { visibility: hidden; opacity: 0;  animation: appear 1s linear 3s forwards }
@keyframes appear {
  to {
	visibility: visible;
	opacity: 1;
  }
}

Applies to all modern campaigns that have a cross placed in the ML-CLOSE container

Set the display time by modifying the CSS declaration
