How do you indicate required fields in web design?

Required fields should be indicated with either a symbol or text, not just color. When providing an indicator for a required field, it should be placed right before the form field. This allows a screen reader to read the indicator to a screen reader user right before the user activates the field.

What does it mean when it says field is required?

When you make a field required, people must enter an answer to the field in order to submit their entry. When someone tries to submit an entry without filling out a required field, we highlight the problematic fields and display an error message to let them know the field is required.
