Other examples

With labels (preview)

Labels for numbers are given inline styling but stacked using pseudo elements with display block. This is to bypass an issue with NVDA where block level elements are dictated separately.

119   Open consultations 
<%= render "govuk_publishing_components/components/big_number", {
  number: 119,
  label: "Open consultations"
} %>

With plus symbol (preview)

In some cases, we want to communicate more than just the flat numeric value eg: 400+. This is why we allow values to be passed as flat strings.

400+   Other agencies and public bodies 
<%= render "govuk_publishing_components/components/big_number", {
  number: "400+",
  label: "Other agencies and public bodies"
} %>
