Where can I find HTML to add role="alert"
to error messages in magento. For example, when a user provides a wrong zip code on checkout page this error message shows up.
<div for="postcode" generated="true" class="mage-error" id="postcode-error">Please enter a valid zip code (Ex: 90602 or 90602-1234).</div>
I would like to add an attribute to the above div tag. Magento version is 2.x.
