Signup 3 block design & features
Signup3 is a full-screen centered registration form built with Shadcn UI. A logo sits above a muted rounded panel that holds a heading, labeled email and password fields, a full-width create account button, and three outlined social buttons for Google, GitHub, and Facebook.
The page uses the default background so the muted panel is the only surface that reads as a container. Inputs sit on a lighter fill inside the panel. Social buttons stack full width with brand icons beside the provider names. Spacing inside the panel is even and compact. The heading is centered at the top of the panel.
The look is a standard social-plus-email signup pattern that uses background contrast instead of a bordered card. Complexity is low. You supply a logo and optional text for the heading, submit label, and social providers.
