Autocomplete attributes are a way for you, the developer, to control how the browser should populate a given form field. For example, if you are expecting a street address you can hint to the browser that you are expecting it by using autocomplete="address-line1"
. This prevents the browser from incorrectly guessing form fields on your website which can result in a poor user experience.
