Overlooked Aspects of Form Design

Forms are the point of contact between users and your service — even a small design oversight can lead to drop-offs. Beyond visual design, a holistic approach covering input assistance and error handling is essential.

Input Assistance Tips

Setting the autocomplete attribute correctly lets browsers auto-fill addresses and email fields. Using inputmode controls which keyboard appears on mobile devices — inputmode="tel" for phone numbers, inputmode="numeric" for postal codes.

When to Show Errors

Rather than showing all errors on submit, validating each field on blur is ideal. However, displaying errors in real time while the user is still typing can backfire — being told "invalid value" before finishing input feels frustrating.
