Users expect toggle switches. Not clunky checkboxes from 2005.
Modern Bootstrap components include a sleek form switch that works out of the box with minimal code.
These Bootstrap toggle switch examples cover everything from basic implementation to advanced customization, including JavaScript event handling, accessible forms markup, and custom styling techniques.
You’ll find working code snippets for default switches, colored variants, size modifications, and icon integration.
Each example uses Bootstrap 5 classes and follows current responsive design practices.
Copy, paste, customize. That’s the goal here.
What is a Bootstrap Toggle Switch
A Bootstrap toggle switch is a form control that lets users flip between two states: on and off.
It replaces the standard Bootstrap checkbox with a sliding switch component.
Built on HTML input elements, the toggle switch uses CSS classes from Bootstrap to create the visual slider effect.
Common use cases include settings panels, dark mode toggles, notification preferences, and feature flags in admin dashboards.

How Does a Bootstrap Toggle Switch Work
The toggle switch wraps a checkbox input inside a .form-check container with the .form-switch modifier class.
When users click the switch, the checked attribute changes state.
JavaScript event listeners capture the onChange event to trigger actions based on the current toggle state.
The sliding animation comes purely from CSS transitions applied to the ::before pseudo-element.
Bootstrap Toggle Switch Styles
Bootstrap 5 provides several styling options for switch components out of the box.
You can customize colors, sizes, and label positions using utility classes or custom CSS variables.
Default Toggle Switch
The default style uses Bootstrap’s primary color scheme with a rounded slider track.
Add .form-check-input to the input and .form-switch to the wrapper.
“ <div class="form-check form-switch"> <input class="form-check-input" type="checkbox" id="defaultSwitch"> <label class="form-check-label" for="defaultSwitch">Enable notifications</label> </div> `
Custom Colored Toggle Switch
Override the default blue with CSS variables or utility classes for brand consistency.
Target the :checked state to change background-color and border-color properties.
` .form-check-input:checked { background-color: #28a745; border-color: #28a745; } `
Toggle Switch with Labels
Position labels before, after, or on both sides of the switch using grid system utilities.
Pair with .form-check-label for proper alignment and click targeting.
How to Create a Bootstrap Toggle Switch
Start with a Bootstrap form container and add the switch markup inside.
The basic structure requires three elements:
- A wrapper div with .form-check
and.form-switchclasses
- An input element with type=”checkbox”
and.form-check-input
- A label element with .form-check-label
linked via theforattribute
Include Bootstrap’s CSS via CDN or npm, then copy this complete example:
` <div class="form-check form-switch"> <input class="form-check-input" type="checkbox" role="switch" id="mySwitch"> <label class="form-check-label" for="mySwitch">Toggle me</label> </div> `
The role=”switch” attribute improves ARIA compatibility for screen readers.
Bootstrap Toggle Switch Sizes
Bootstrap doesn’t include built-in size variants for switches, but you can create them with custom CSS.
Scale the switch proportionally by adjusting width, height, and the slider dimensions together.
Small Toggle Switch
Reduce the switch to 75% of default size for compact user interface layouts.
` .form-switch-sm .form-check-input { width: 2rem; height: 1rem; } `
Large Toggle Switch
Increase dimensions to 150% for touch-friendly mobile interfaces or prominent settings pages.
` .form-switch-lg .form-check-input { width: 4rem; height: 2rem; } `
Pair larger switches with responsive typography to maintain visual balance.
How to Add Icons to Bootstrap Toggle Switches
Icons inside toggle switches provide instant visual feedback for the on/off states.
Use Bootstrap Icons or SVG elements positioned with CSS pseudo-elements.
Place checkmark icons for “on” and X icons for “off” states:
` .form-check-input:checked::before { content: "f26e"; / Bootstrap Icons checkmark / font-family: "bootstrap-icons"; position: absolute; color: white; }
.form-check-input:not(:checked)::before { content: “f62a”; / Bootstrap Icons X / font-family: “bootstrap-icons”; } `
Inline SVG works better for cross-browser compatibility than icon fonts.
Bootstrap Toggle Switch with JavaScript Events
Capture user interactions with the onChange event to trigger real-time updates.
Query the input element and attach an event listener:
` const toggle = document.getElementById('mySwitch');
toggle.addEventListener(‘change’, function() { if (this.checked) { console.log(‘Switch is ON’); // Trigger your action here } else { console.log(‘Switch is OFF’); } }); `
Common use cases for JavaScript event handling:
- Dark mode activation with DOM manipulation
- Form validation state updates
- Sending Ajax requests to save preferences
- Toggling visibility of page sections
Add micro-interactions like haptic feedback or sound effects to improve user experience.
Bootstrap Toggle Switch Accessibility
Web accessibility for toggle switches requires proper labeling, keyboard support, and screen reader compatibility.
Always include these ARIA labels and attributes:
- role=”switch”
tells assistive technology this is a toggle, not a checkbox
- aria-checked
reflects the current state dynamically
- aria-label
or visible label for context
` <div class="form-check form-switch"> <input class="form-check-input" type="checkbox" role="switch" aria-checked="false" id="accessibleSwitch"> <label class="form-check-label" for="accessibleSwitch"> Enable dark mode </label> </div> `
Keyboard navigation works natively with Tab to focus and Space to toggle.
Test with screen readers like NVDA, JAWS, and VoiceOver per web accessibility checklist guidelines.
Maintain sufficient color contrast between the switch track and background, minimum 3:1 ratio for WCAG AA compliance.
Common Bootstrap Toggle Switch Errors
Most toggle switch issues stem from missing classes, incorrect markup structure, or JavaScript conflicts.
Quick fixes for the most frequent problems:
| Error | Cause | Solution | | — | — | — | | Switch shows as regular checkbox | Missing .form-switch class | Add class to parent .form-check div | | Label not clickable | for attribute doesn't match input id | Sync the for and id values | | Switch not sliding | Bootstrap CSS not loaded | Check CDN link or npm import | | onChange not firing | Event listener attached before DOM ready | Wrap in DOMContentLoaded event | | Disabled state not working | Missing disabled attribute on input | Add disabled to the input element | | Custom colors not applying | CSS specificity too low | Use !important or increase selector specificity |
Check the browser console for frontend errors if the switch fails silently.
Validate your HTML markup structure matches Bootstrap 5 documentation exactly.
FAQ on Bootstrap Toggle Switch Examples
What is a Bootstrap toggle switch?
A Bootstrap toggle switch is a form control that replaces standard checkboxes with a sliding on/off switch. It uses the .form-switch class combined with .form-check to create the visual slider effect in Bootstrap 5.
How do I create a basic toggle switch in Bootstrap 5?
Wrap a checkbox input with .form-check and .form-switch classes. Add .form-check-input to the input element and .form-check-label to the label. Link them using matching for and id attributes.
Can I change the color of a Bootstrap toggle switch?
Yes. Override the background-color and border-color properties on .form-check-input:checked using custom CSS. You can also use CSS variables or Bootstrap animations for smooth color transitions between states.
How do I make a Bootstrap toggle switch disabled?
Add the disabled attribute directly to the input element. Bootstrap automatically applies muted styling and prevents user interaction. The disabled state also blocks JavaScript click events from firing on the switch.
What JavaScript event does a toggle switch use?
Toggle switches fire the change event when users flip the switch. Attach an event listener with addEventListener(‘change’, callback) and check this.checked to determine the current boolean toggle state.
How do I make a toggle switch accessible?
Add role=”switch” to the input for screen readers. Include aria-checked that updates dynamically. Pair with visible labels using the for attribute. Follow inclusive design practices for keyboard navigation support.
Can I add icons to a Bootstrap toggle switch?
Yes. Use CSS ::before pseudo-elements with icon fonts or inline SVG. Position icons absolutely within the switch track. Show different icons for checked and unchecked states using the :checked selector.
How do I change the size of a Bootstrap toggle switch?
Bootstrap 5 lacks built-in size variants. Create custom classes like .form-switch-sm or .form-switch-lg that adjust width, height, and slider dimensions proportionally. Match label font sizes for visual hierarchy.
Why is my Bootstrap toggle switch not working?
Common causes include missing Bootstrap CSS, incorrect class names, or mismatched for/id attributes. Check that .form-switch is on the wrapper div, not the input. Verify your Bootstrap version supports form switches.
Can I use toggle switches inside Bootstrap modals or forms?
Yes. Toggle switches work inside any Bootstrap container including Bootstrap modal dialogs, Bootstrap cards, and complex form layouts. No additional configuration needed beyond standard markup structure.
