Common Design Elements in Bootstrap

Bootstrap provides a rich library of reusable components and utilities that make designing user interfaces faster and easier. Below are some of the most commonly used elements:

1. Grid System

The grid system in Bootstrap is based on a 12-column layout, allowing you to create responsive designs by defining column widths for different screen sizes.

<div class="container">
    <div class="row">
        <div class="col-md-6">Column 1</div>
        <div class="col-md-6">Column 2</div>
    </div>
</div>

2. Buttons

Bootstrap provides a variety of button styles that can be customized using utility classes.

<button class="btn btn-primary">Primary</button>
<button class="btn btn-secondary">Secondary</button>
<button class="btn btn-danger">Danger</button>

3. Forms

Forms are styled with consistent spacing and alignment for better usability.

<form>
    <div class="mb-3">
        <label for="email" class="form-label">Email address</label>
        <input type="email" class="form-control" id="email" placeholder="Enter your email">
    </div>
    <div class="mb-3">
        <label for="password" class="form-label">Password</label>
        <input type="password" class="form-control" id="password" placeholder="Enter your password">
    </div>
    <button type="submit" class="btn btn-success">Submit</button>
</form>

4. Navigation Bar

The navigation bar is a versatile component for building headers and menus.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <div class="container-fluid">
        <a class="navbar-brand" href="#">Brand</a>
        <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarNav">
            <ul class="navbar-nav">
                <li class="nav-item">
                    <a class="nav-link active" href="#">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Features</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Pricing</a>
                </li>
            </ul>
        </div>
    </div>
</nav>

5. Cards

Cards are flexible content containers for displaying information.

<div class="card" style="width: 18rem;">
    <img src="https://via.placeholder.com/150" class="card-img-top" alt="Card Image">
    <div class="card-body">
        <h5 class="card-title">Card Title</h5>
        <p class="card-text">Some quick example text to build on the card title.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
    </div>
</div>

6. Modals

Modals are used for dialogs, alerts, and other interactions.

<button type="button" class="btn btn-warning" data-bs-toggle="modal" data-bs-target="#exampleModal">
    Open Modal
</button>

<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="exampleModalLabel">Modal Title</h5>
                <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
            </div>
            <div class="modal-body">
                This is the content of the modal.
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>
