Which of the following components is used to customize a community's appearance?

The Builder component is primarily designed for customizing a community's appearance in the Experience Cloud. It provides an intuitive drag-and-drop interface that allows users to modify layouts, add components, and customize branding elements such as logos, colors, and fonts without needing extensive coding knowledge. This capability enables admins and designers to create a tailored experience that reflects their organization’s branding and meets the specific needs of their community members.

User Profiles are important for managing access and permissions within the community but do not directly influence how the community looks. Content Management focuses on organizing and managing the content within the community rather than its visual design. Moderation is centered around controlling interactions and managing user-generated content, which, while important for community dynamics, does not pertain to the customization of appearance. Thus, Builder stands out as the tool specifically intended for visual customization within the Experience Cloud.
