HTML FORM ► MacroNepal

HTML Structure

Container: Holds the login and registration 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.
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…”
