In Bootstrap 5 (BS5), cards are flexible and extensible content containers. They include options for headers, footers, images, and various content types like text, lists, and links.

? Basic Card

<div class="card" style="width: 18rem;">  <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>

?? Card with Image

<div class="card" style="width: 18rem;">  <img src="https://via.placeholder.com/286x180" class="card-img-top" alt="...">  <div class="card-body">    <h5 class="card-title">Card with Image</h5>    <p class="card-text">Supporting text below as a natural lead-in.</p>    <a href="#" class="btn btn-primary">Explore</a>  </div></div>

? Card Header & Footer

<div class="card text-center">  <div class="card-header">    Featured  </div>  <div class="card-body">    <h5 class="card-title">Special title</h5>    <p class="card-text">With supporting text.</p>    <a href="#" class="btn btn-primary">Action</a>  </div>  <div class="card-footer text-muted">    2 days ago  </div></div>

? Cards with List Groups

<div class="card" style="width: 18rem;">  <div class="card-header">    List  </div>  <ul class="list-group list-group-flush">    <li class="list-group-item">Item 1</li>    <li class="list-group-item">Item 2</li>    <li class="list-group-item">Item 3</li>  </ul></div>

? Card Layouts with Grid

Use .row and .col classes for card decks or grids.

<div class="row row-cols-1 row-cols-md-3 g-4">  <div class="col">    <div class="card h-100">      <img src="https://via.placeholder.com/300x180" class="card-img-top" alt="...">      <div class="card-body">        <h5 class="card-title">Card title</h5>        <p class="card-text">Card with equal height using h-100.</p>      </div>    </div>  </div>  <!-- Repeat cols for more cards --></div>

? Card with Image Overlay

<div class="card bg-dark text-white">  <img src="https://via.placeholder.com/500x250" class="card-img" alt="...">  <div class="card-img-overlay">    <h5 class="card-title">Overlay Title</h5>    <p class="card-text">Text over image.</p>  </div></div>
