Login and Registration UI
Authentication screens benefit from simple Bootstrap containers, form controls, validation feedback, and clear action hierarchy.
Core concept
Build a centered login form with email, password, remember-me control, primary submit button, and recovery link. Explain why the form should remain usable without relying on placeholder text.
Using it in a real interface
Extend the pattern into registration with grouped fields and validation feedback. Explain how server errors and client-side validation can coexist without confusing the user.
Implementation notes
Keep authentication pages focused. Avoid unnecessary navigation, decorative content that distracts from the form, and error messages that reveal sensitive account information.
