#   {{ cms:children }}
#   {{ cms:children style: "font-weight: bold", exclude: "404-page, search-page" }}

# #children {
#   color: #006633;
#   font-size: 90%;
#   margin-bottom: 4px;
#   font-style: italic;
# }
# and/or pass in style overrides with the 'style' parameter, as above
#
# To exclude children, list their slugs with the 'exclude' parameter
# as comma-delimited string, e.g. as above - exclude: "404-page, search-page"
