Blockquotes: All quotation marks after the first one are single quotation marks

[mjendruk]

All encircled quotation marks used to highlight block quotes are single quotation marks. According to this website (https://css-tricks.com/almanac/properties/q/quotes/), “open-quote” needs to be closed by a “close-quote” or “no-close-quote”. Adding the following snippet into the css file fixes it:

blockquote:after {
    content: no-close-quote;
}
