To create an accessible online form, you must ensure that all form fields have accurate labels or prompts so screen reader users know what each field is asking for. Forms typically have labels or prompts that are obvious to sighted users, but their association with particular form fields is made based on visual cues, such as relative position and proximity to the field. Since screen reader users don’t have access to these same visual cues, labels and prompts must be explicitly associated with form fields within the HTML. Following are a few techniques for accomplishing this.
Making PDF Forms Accessible
Interactive forms in Adobe PDF have many of the same issues as those described above. Labels and prompts must all be created in a way that explicitly associates them with their corresponding form fields. Also, PDF form fields have a tendency to be out of order, so you must be sure to test the tab order of your form, to be sure that users will move through the form in a logical sequence when jumping between fields using the keyboard.
