Re: Mandatory fields

Hi Sarah,

An asterisk without an explanation is not a sufficient description.

The error messages are not helpful for example if a field for a day, telephone number or something similar expects a certain order and special characters like mm/dd/yy or dd.mm.yyyy - these things have to be explained.

Also the error messages of browsers are not visually connected with the mandatory input. If a user accidentally scrolls a little bit, they end up staying next to another input which might be not mandatory at all.

Explaining the asterisk after its appearance (visually, in DOM or in the accessibility tree) violates meaningful order.

For users that can see there must be a visual indication of required fields; for users of assistive technology a programmatically determinable connection between the information and the input has to be provided. For example the required attribute or a text in the label.

It’s good practice to hide the asterisk (and the description for the asterisk) from screenreader users. If you inform them with a different technique anyway (like the required attribute) this would be redundant clutter.
