Introduction:

A login form is an essential element of any website that requires user authentication. Bootstrap 5 is the latest version of the popular front-end framework that is widely used for building responsive and mobile-first websites. In this tutorial, we will guide you through the process of creating a Bootstrap 5 login form step by step.

Getting Started with Bootstrap 5:

Before we dive into building the login form, let's take a quick look at Bootstrap 5. Bootstrap is a free and open-source CSS framework that provides a set of pre-designed components and utilities for building responsive websites. Bootstrap 5 comes with several new features, including a revamped grid system, a new set of utility classes, and a streamlined CSS structure.

To get started with Bootstrap 5, you need to include the CSS and JavaScript files in your HTML document. You can either download the files from the official Bootstrap website or use a CDN (Content Delivery Network) to load them from a remote server.

Creating a Bootstrap 5 Login Form:

To create a Bootstrap 5 login form, we need to use a combination of HTML and Bootstrap classes. Here's a basic login form structure:
 

<form>
 <div class="mb-3">
   <label for="username" class="form-label">Username</label>
   <input type="text" class="form-control" id="username" placeholder="Enter username">
 </div>
 <div class="mb-3">
   <label for="password" class="form-label">Password</label>
   <input type="password" class="form-control" id="password" placeholder="Enter password">
 </div>
 <button type="submit" class="btn btn-primary">Login</button>
</form>

 

This code creates a simple login form with two input fields for the username and password, and a submit button. We've used the Bootstrap form control and form label classes to style the input fields and labels.

Adding Form Validation with jQuery:

Now that we've created the basic structure of the login form, we need to add form validation to ensure that the user inputs are valid. We can use jQuery to validate the form and display error messages if necessary. Here's an example code for validating the username field:
 

$(document).ready(function() {
 $('#login-form').submit(function(e) {
   e.preventDefault();
   var username = $('#username').val();
   if (username.length == 0) {
     $('#username-error').text('Username is required');
     return false;
   }
   return true;
 });
});

In this code, we're using the submit event of the form to validate the username field. If the username field is empty, we're displaying an error message next to the field using the jQuery text() function. We're also preventing the form from submitting if there are any validation errors.

Styling the Login Form:

Now that we have a functional login form with form validation, we can apply some styling to make it more visually appealing. We can use Bootstrap classes to customize the form's appearance and add some extra features such as a remember me checkbox or a forgot password link.
Here's an example of how to style the login form using Bootstrap classes:

<form>
 <div class="mb-3">
   <label for="username" class="form-label">Username</label>
   <input type="text" class="form-control" id="username" placeholder="Enter username">
   <div id="username-error" class="invalid-feedback"></div>
 </div>
 <div class="mb-3">
   <label for="password" class="form-label">Password</label>
   <input type="password" class="form-control" id="password" placeholder="Enter password">
   <div id="password-error" class="invalid-feedback"></div>
 </div>
 <div class="mb-3 form-check">
   <input type="checkbox" class="form-check-input" id="remember-me">
   <label class="form-check-label" for="remember-me">Remember me</label>
 </div>
 <button type="submit" class="btn btn-primary">Login</button>
 <a href="#" class="link-secondary">Forgot password?</a>
</form>

 

 

In this code, we've added a Bootstrap invalid-feedback class to display error messages next to the input fields. We've also added a form-check class to the remember me checkbox and a link-secondary class to the forgot password link to style them according to Bootstrap's default styles.
