Source: callout-email.css

Use this callout to create email-like callouts. Any nested callout will be given the visual effect of an input, so best is to keep them at the beginning. To have a separator, add sep as an option of your last nested callout, this will give it a bottom border.

After copying this template, remove the  . They are non-breakable space that are only here as placeholders to insure each callout has a content (and the dotted underlines).
