The front-end is the presentation layer or user interface that the visitor interacts with on a website. It also defines what client-side A/B testing tools that use What You See Is What You Get (WYSIWYG) visual editors have the ability to manipulate. Such software is not able to alter the back-end and so A/B tests that involve making changes to the back-end require developer resource. Also see back-end and client-side. Also see back end.
