# Customize Sightline Precheck look & feel

You can customize how Sightline Precheck looks to your users when it’s presented to them. Customization isn’t required, and Precheck will use HUMAN defaults if you don’t edit them.

> **Warning**
>
> Precheck is available with [Custom ABR](/applications/set-challenge-configurations#custom-abr) for web and HTML properties, but is incompatible with Custom ABR for API.

## Prerequisites
