You have -webkit-column-width: 1px dotted red; You need -webkit-column-rule: 1px dotted red;

style.css 
/* Complete the challenge by writing CSS below */

.main {
  -webkit-column-count: 2;
  -webkit-column-gap: 2.5em;
  -webkit-column-rule: 1px dotted red;
}

Or, if you wanted to set each property individually, you could set it like so:

style.css 
/* Complete the challenge by writing CSS below */

.main {
  -webkit-column-count: 2;
  -webkit-column-gap: 2.5em;
  -webkit-column-rule-width: 1px;
  -webkit-column-rule-style: dotted; 
  -webkit-column-rule-color: red;
}
