Before & After captions

It’s easy and would be nice to see a plugin update with this feature and customizable labels using shortcode parameters.

For the moment you can overwrite your local js library
/wp-content/plugins/twenty20/assets/js/jquery.twenty20.js

with the version from
https://github.com/zurb/twentytwenty/blob/master/js/jquery.twentytwenty.js

then if you want to change the default before/after labels you can do it adding a couple of CSS rules in your styles

.twentytwenty-before-label:before { content: “NEW BEFORE LABEL”; }
.twentytwenty-after-label:before { content: “NEW AFTER LABEL”; }
