Layouts Of Forms In Bootstrap

Bootstrap offers various form layouts to help you create clean and responsive forms easily. Here’s a simple guide to understanding them:

Vertical Form Layout (Default)

A Vertical form in Bootstrap includes text fields, checkboxes, and buttons. By default, these elements are stacked vertically, one on top of the other. This layout is straightforward and works well for simple forms. Let us see a basic example of a code below, understanding how you can create a vertical form in Bootstrap.
<!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-8">     <meta name="viewport" content="width=device-width, initial-scale=1.0">     <title>Sign Up Form</title>    </head> <body> <div class="container mt-5">     <div class="row justify-content-center">         <div class="col-md-4">             <form>                 <div class="form-group">                     <label for="firstName">First Name</label>                     <input type="text" class="form-control" id="firstName" placeholder="First name">                 </div>                 <div class="form-group">                     <label for="lastName">Last Name</label>                     <input type="text" class="form-control" id="lastName" placeholder="Last name">                 </div>                 <div class="form-group">                     <label for="email">Email</label>                     <input type="email" class="form-control" id="email" placeholder="Your email">                 </div>                 <div class="form-group">                     <label for="password">Password</label>                     <input type="password" class="form-control" id="password" placeholder="Your password">                 </div>                 <button type="submit" class="btn btn-primary">Sign up</button>             </form>         </div>     </div> </div> <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.2/dist/umd/popper.min.js"></script> </body> </html>

Horizontal Form Layout

A horizontal form layout places labels and form fields side by side, making better use of horizontal space. This is especially useful for longer forms, as it reduces the overall length of the page. You can create this layout by using Bootstrap’s grid system and classes like form-horizontal and form-group.
<!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-8">     <meta name="viewport" content="width=device-width, initial-scale=1.0">     <title>Horizontal Form</title>     <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <div class="container mt-5">     <form>         <div class="form-row align-items-center">             <div class="col-auto">                 <label class="sr-only" for="firstName">First Name</label>                 <input type="text" class="form-control mb-2" id="firstName" placeholder="First name">             </div>             <div class="col-auto">                 <label class="sr-only" for="lastName">Last Name</label>                 <input type="text" class="form-control mb-2" id="lastName" placeholder="Last name">             </div>             <div class="col-auto">                 <label class="sr-only" for="email">Email</label>                 <input type="email" class="form-control mb-2" id="email" placeholder="Your email">             </div>             <div class="col-auto">                 <label class="sr-only" for="password">Password</label>                 <input type="password" class="form-control mb-2" id="password" placeholder="Your password">             </div>             <div class="col-auto">                 <button type="submit" class="btn btn-primary mb-2">Sign up</button>             </div>         </div>     </form> </div> <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.2/dist/umd/popper.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script> </body> </html>

Inline Form Layout

An inline form layout displays form elements in a single line. This is ideal for search bars or quick input forms where space is limited. Use the form-inline class to achieve this compact layout.
<!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-8">     <meta name="viewport" content="width=device-width, initial-scale=1.0">     <title>InLine Form</title>     <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <div class="container mt-5">     <h2>Signup</h2>     <form class="form-inline">         <div class="form-group mb-2">             <label for="name" class="sr-only">Name</label>             <input type="text" class="form-control" id="name" placeholder="Enter name">         </div>         <div class="form-group mx-sm-3 mb-2">             <label for="email" class="sr-only">Email</label>             <input type="email" class="form-control" id="email" placeholder="Enter email">         </div>         <div class="form-group mb-2">             <label for="password" class="sr-only">Password</label>             <input type="password" class="form-control" id="password" placeholder="Enter password">         </div>         <button type="submit" class="btn btn-primary mb-2">Register</button>     </form> </div> <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.2/dist/umd/popper.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script> </body> </html>
