add ellipsis for long text code example

Example 1: text overflow ellipsis 1 line

.truncate {
  width: 250px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

Example 2: show ellipsis after text length

max-width: 100px;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
// div in a flex - assign width% , no need of even max-width !
