Pull Request: https://github.com/php/web-php/pull/966 Author: haszi
There is now one caption (as in a `<caption>` tag in docbook) used in `doc-en` under the `xkcd` image on [`goto`'s page](https://www.php.net/manual/en/control-structures.goto.php). I've already opened a PR for Phd ([here](https://github.com/php/phd/pull/109)) which wraps the text of the caption in a `div` with the class `caption`. This PR adds formatting to that class.
