Re: Using required attribute with a star mark VS Marking as optional


From: Birkir R. Gunnarsson

The big difference is that using the HTmL5 required attribute triggers
browser validation of the form in browsers that support HTML5.
This should be a good thing, but the browsers do a poor job of
presenting accessible error messages (the browser vendors should do a
better job of this, in my opinion).
Using the asterisk to mark required form fields does not trigger
validation of any kind, the validation is left up to the website
Using aria-required does not either.
You can still take advnaage of the browser validation and transform
the display of the browser error messages into something more
accessible, I've coded up a ew examples I just need to find the time
to put one up on Code Pen.
I'll post back to this threat if I get this done.
Basically, if all fields are required, just have text at the top of
the form that says all tields are required.
If one or two fields are optional, change the instructions to "all
fields are required unless marked optional", and include the word
(optional) in the <label> tag for those fields.
Try to avoid optional fields, not for accessibility but for UX, users
don't want to spend all day filling in forms, they want to get the
task done, so make it as easy as possible for them.
