Examples
Centered authentication page
Places the demo in the center of a full-height authentication screen.
centered-authentication-page.tsx
import LoginForm from "@/registry/magicui/border-beam-demo-3"export default function AuthPage() { return ( <main className="flex min-h-screen items-center justify-center p-6"> <LoginForm /> </main> )}Login card in an account layout
Uses the example as the primary content of a responsive account-access section.
login-card-in-an-account-layout.tsx
import LoginForm from "@/registry/magicui/border-beam-demo-3"export default function AccountAccess() { return ( <section className="grid min-h-screen place-items-center bg-muted/30 p-4"> <div className="w-full max-w-md"> <LoginForm /> </div> </section> )}Accessibility
- The Email and Password labels are explicitly associated with their inputs through matching htmlFor and id values.
- The email and password controls use appropriate input types, enabling browser validation and suitable virtual-keyboard behavior.
- The form fields are grouped in a semantic form element.
- The Register and Login controls are rendered as buttons by the shadcn Button component; add application-specific form handling and validation when integrating.
- The animated border is decorative; ensure the surrounding page provides an accessible heading or context if this example is used as a standalone screen.
- Consider honoring prefers-reduced-motion in the BorderBeam implementation or surrounding application if animated effects may distract users.
