    FAQs for Labels and Instructions (A)

    How to label elements and give instructions?

    Label all input fields clearly and helpfully.
    Where a field needs a specific format, give an example (For example, for a ‘date’ field in a form you might use ‘Enter the date as dd/mm/yyyy’)
    Mark required fields with an icon and explain what the icon means before the form.
    Keep your labels simple – too much explanation can be counter-productive. Things like ‘First name’, ‘Email’ and ‘Your message’ are fine.
    The same goes for instructions, ‘Required fields are in red and have a * symbol’ works great. So does ‘Fill in this form and click ‘Submit’ to get in touch’.

    Best practices for labels and instructions.

    Instructions need to take into account how they use sensory characteristics.
    Think about how your use of colour affects things like required fields if you want to highlight them by colour. Don’t highlight by colour alone, pick a symbol too.
    Consider error identification as well, and make sure that you give helpful instructions when your users make mistakes on forms.
