Very good - on underlining links

We shouldn’t rely on colour alone to indicate that something is interactive.

Take links, for example. Sure, you can give them a different colour to the surrounding text, but you shouldn’t stop there. Make sure there’s something else that distinguishes them. You could make them bold. Or you could stick with the well-understood convention of underlying links.

Forms are how websites interact with users and can help your organization grow. Think about the forms on your own website or that you use to interact with your favorite companies. For example, login, payment, or event registration forms just to name a few.

Obviously, forms are important to get right. We don’t want a user’s experience to be frustrating or lead to them not being able to complete the form. That can mean the loss of a sale, customer, attendee, or confidence in the organization.

In this article, we’ll briefly go over form functionality that websites often don’t consider. These strategies can make your forms more usable for all users and accessible for users with disabilities.
