HTML Structure
- Container: Holds the
login
andregistration
forms. - Forms:
- Login Form: Includes fields for email and password, a login button, social login buttons (Facebook, Google, GitHub), and a toggle link to switch to the registration form.
- Registration Form: Contains fields for full name, address, age, email, and password, a register button, and a toggle link to switch back to the login form.
- Background Element: Adds a gradient and animated glow effect behind the forms.
CSS Styling and Effects
- Basic Styles:
- A linear gradient background color and a radial gradient effect for the form background.
- Animated glow effect (
@keyframes glow
) that subtly changes the form container’s shadow and size. - The background glow animates between scales, adding to the immersive look.
- Form Styling:
- Smooth transitions and animations on focus states for input fields.
- Button transformations on hover, creating a glowing effect.
- Toggle links that switch between the forms with a fade animation.
- Social Login Buttons: Styled with colors for specific platforms and scale-up on hover.
- Responsive Design: The forms are centered and responsive to different screen sizes, with flexible max-widths.
JavaScript Functionality
- Form Toggle:
toggleForm()
: Toggles between displaying the login and registration forms, creating a seamless switch effect.
- Login Functionality:
- Validates the email and password input by checking against
localStorage
to see if there’s a match for an existing user. - If matched, a success message is displayed; if not, an error message appears.
- Validates the email and password input by checking against
- Registration Functionality:
- Validates fields to ensure all are filled and checks age for validity.
- Password Validation: Ensures it includes an uppercase letter, lowercase letter, number, and special symbol.
- Saves user data (name, address, age, email, password) to
localStorage
in lowercase for consistent comparison during login. - After successful registration, it displays a success message and toggles to the login form.
- Social Login Simulation:
socialLogin(platform)
: Simulates logging in with social media platforms with an alert, e.g., “Logging in with Facebook…”
