How to call this component
<%= render "govuk_publishing_components/components/error_message", {
text: "Please enter your National Insurance Number",
id: "error_id"
} %>
GOV.UK Design System
This component incorporates components from the GOV.UK Design System:
Accessibility acceptance criteria
All text must have a contrast ratio higher than 4.5:1 against the background colour to meet WCAG AA
Error message must:
- be associated with an input. The
error_message_id
must match thearia-describedby
property on the input your label is associated with. Note that ifid
is not passed to the component an id will be generated automatically.
If error message is within a label it will be announced in its entirety by screen readers. By associating error messages with inputs using aria-describedby
, then screen readers will read the label, describe the type of input (eg radio) and then read additional text. It means users of screen readers can scan and skip options as easy as people making choices with sight.

{
text: "Error 2"
