---

Form controls have global styling defined at the HTML element level. Labels and most input types are 100% width of the <form> parent element.

Validation

To use form validation feedback - which includes feedback messages, icons and border colours - wrap individual input elements in a p-form-validation and additionally apply the .is-error, .is-caution or .is-success to the wrapper as appropriate.

If your form uses select elements then you will additionally need to wrap only the <select> element in a wrapper with the class p-form-validation__select-wrapper to mitigate some of the quirks of this specific HTML element across browsers.

Descriptive text relating to the element’s validation status should use the class p-form-validation__message.

Required

By applying the class .is-required the attribute specifies that an input field must be filled out before submitting the form.
