aria-required attribute is used to indicate to screen reader users that a form input is required. As there is now in HTML a general
required attribute which works with most user agents, it’s unnecessary to use both at the same time. In general, you can rely solely on the
required attribute, unless you want to provide backwards compatibility on old screen reader software versions.
<form action="order."> <!-- This will raise a warning on unnecesary attributes --> <input id="city" name="city" aria-required="true" required /> <!-- You can use this instead --> <input id="city" name="city" required /> </form>
