In today’s web development landscape, providing a smooth and intuitive user experience is essential, especially when it comes to something as important as user authentication. In this post, we’ll walk through the process of building a clean, responsive login and registration form. We’ll cover everything from the basic HTML structure to the subtle design touches that make your forms feel modern and user-friendly. Let’s dive in!
Getting Started: The HTML Structure
We begin with a basic HTML5 structure that sets the stage for our login and register forms. Here’s a brief look at the code snippet that forms our foundation:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- BOXICONS -->
<link href='https://unpkg.com/boxicons@2.1.4/css/boxicons.min.css' rel='stylesheet'>
<!-- CSS -->
<link rel="stylesheet" href="css/style.css">
<title>Login & Register | Ludiflex</title>
</head>
<body>
<div class="wrapper">
<div class="form-header">
<div class="titles">
<div class="title-login">Login</div>
<div class="title-register">Register</div>
</div>
</div>
<!-- LOGIN FORM -->
<form action="#" class="login-form" autocomplete="off">
<!-- Login form inputs -->
</form>
<!-- REGISTER FORM -->
<form action="#" class="register-form" autocomplete="off">
<!-- Register form inputs -->
</form>
</div>
<script src="js/script.js"></script>
</body>
</html>
Key Points in Our HTML:
- Semantic Markup: The use of semantic HTML elements such as
<form>and<input>helps improve accessibility and maintainability. - Responsive Design: The meta viewport tag ensures our forms render well on different devices.
- External Libraries: We link to Boxicons for attractive iconography, which enhances the overall user experience.
- Styles and Scripts: External CSS (
css/style.css) and JavaScript (js/script.js) files allow us to keep our HTML clean and our code modular.
Crafting the Login Form
Let’s take a closer look at the login form. Notice how each input field is wrapped in an input-box div that includes not only the <input> element but also a <label> and an icon:
<!-- LOGIN FORM -->
<form action="#" class="login-form" autocomplete="off">
<div class="input-box">
<input type="text" class="input-field" id="log-email" required>
<label for="log-email" class="label">Email</label>
<i class='bx bx-envelope icon'></i>
</div>
<div class="input-box">
<input type="password" class="input-field" id="log-pass" required>
<label for="log-pass" class="label">Password</label>
<i class='bx bx-lock-alt icon'></i>
</div>
<div class="form-cols">
<div class="col-1"></div>
<div class="col-2">
<a href="#">Forgot password?</a>
</div>
</div>
<div class="input-box">
<button class="btn-submit" id="SignInBtn">Sign In <i class='bx bx-log-in'></i></button>
</div>
<div class="switch-form">
<span>Don't have an account? <a href="#" onclick="registerFunction()">Register</a></span>
</div>
</form>
Highlights:
- Floating Labels: The labels for each input are placed after the input element, which can be styled to create a floating label effect. This not only looks modern but also improves usability.
- Icon Usage: Using icons (via Boxicons) next to each input field adds a visual cue that helps users quickly understand what each field represents.
- User Flow: A “Forgot password?” link is included, and there’s an easy transition to the registration form with a call-to-action at the bottom.
Building the Register Form
The registration form follows a similar structure but includes a few additional elements to accommodate the registration process:
<!-- REGISTER FORM -->
<form action="#" class="register-form" autocomplete="off">
<div class="input-box">
<input type="text" class="input-field" id="reg-name" required>
<label for="reg-name" class="label">Username</label>
<i class='bx bx-user icon'></i>
</div>
<div class="input-box">
<input type="text" class="input-field" id="reg-email" required>
<label for="reg-email" class="label">Email</label>
<i class='bx bx-envelope icon'></i>
</div>
<div class="input-box">
<input type="password" class="input-field" id="reg-pass" required>
<label for="reg-pass" class="label">Password</label>
<i class='bx bx-lock-alt icon'></i>
</div>
<div class="form-cols">
<div class="col-1">
<input type="checkbox" id="agree">
<label for="agree"> I agree to terms & conditions</label>
</div>
<div class="col-2"></div>
</div>
<div class="input-box">
<button class="btn-submit" id="SignUpBtn">Sign Up <i class='bx bx-user-plus' ></i></button>
</div>
<div class="switch-form">
<span>Already have an account? <a href="#" onclick="loginFunction()">Login</a></span>
</div>
</form>
Highlights:
- Additional Fields: The registration form includes an extra field for the username, which is often required during sign-up.
- Terms and Conditions: There’s a checkbox for users to agree to the terms and conditions. This small detail is crucial for compliance and user trust.
- Smooth Navigation: Just like the login form, there’s a clear call-to-action that encourages users who already have an account to log in, creating a seamless transition between the two forms.
Enhancing the Experience with CSS and JavaScript
CSS Styling
While our HTML provides the structure, CSS brings our forms to life. In your css/style.css file, you can define styles for the wrapper, forms, input fields, and buttons. Some useful CSS techniques include:
- Flexbox or Grid: Use these layout models to center your forms and ensure they’re responsive.
- Transitions and Animations: Smooth transitions on focus or hover states for inputs and buttons improve the user experience.
- Responsive Design: Media queries help adapt the form layout to various screen sizes, ensuring usability on mobile devices.

JavaScript Interactivity
In the snippet above, you might have noticed functions like registerFunction() and loginFunction(). These functions (defined in your js/script.js file) handle the transition between the login and registration forms. A simple implementation could involve toggling the visibility of each form:
const loginForm = document.querySelector(".login-form");
const registerForm = document.querySelector(".register-form");
const wrapper = document.querySelector(".wrapper");
const loginTitle = document.querySelector(".title-login");
const registerTitle = document.querySelector(".title-register");
const signUpBtn = document.querySelector("#SignUpBtn");
const signInBtn = document.querySelector("#SignInBtn");
function loginFunction(){
loginForm.style.left = "50%";
loginForm.style.opacity = 1;
registerForm.style.left = "150%";
registerForm.style.opacity = 0;
wrapper.style.height = "500px";
loginTitle.style.top = "50%";
loginTitle.style.opacity = 1;
registerTitle.style.top = "50px";
registerTitle.style.opacity = 0;
}
function registerFunction(){
loginForm.style.left = "-50%";
loginForm.style.opacity = 0;
registerForm.style.left = "50%";
registerForm.style.opacity = 1;
wrapper.style.height = "580px";
loginTitle.style.top = "-60px";
loginTitle.style.opacity = 0;
registerTitle.style.top = "50%";
registerTitle.style.opacity = 1;
}
