Does HTML5 allow the fieldset without the legend, as noted below, and if so then, it would still fail based on H71
Yes it does and no it isn't a failure. The fieldset doesn't mean anything without a legend but there is nothing preventing it from being used on its own (although don't know why someone would bother). It is only really useful when it is used in combination with legend to associate text to a group of form fields.
Thank you Paul
I will go ahead and close
Fieldset can also be used to easily disable a set of form fields. It is very useful even without a legend.
Actually when i had used legend without fieldset ,it is not working
so i can say that legend is nothing without fieldset.
