how can I add blockquote after on my wordpress site

Hi,
on this page here http://alltone.barefruit.com.au/
i have added some blockquote quotation marks at the beginning of the quote.  How do I add a styling for after?
It looks weird without closing quotations??
Can someone help please?

blockquote {
  margin: 1.5em 10px;
  padding: 0.5em 10px;
  quotes: "\201C""\201D""\2018""\2019";
}
blockquote:before {
  color: #ccc;
  content: open-quote;
  font-size: 4em;
  line-height: 0.1em;
  margin-right: 0.25em;
  vertical-align: -0.4em;
}
blockquote p {
  display: inline;
}
