<p>Custom forms in Bootstrap 4 use the <code>custom-control</code> classes to create visually appealing and functional form controls like checkboxes, radio buttons, and file inputs. By using these classes, you can easily create custom-styled components while leveraging Bootstrap's grid and utility classes for layout and design.</p>
<h2>Custom Checkboxes</h2>
