Approach
Browser default checkboxes and radios are replaced with the help of .form-check
, a series of classes for both input types that improves the layout and behavior of their HTML elements, that provide greater customization and cross browser consistency. Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.
Structurally, our <input>
s and <label>
s are sibling elements as opposed to an <input>
within a <label>
. This is slightly more verbose as you must specify id
and for
attributes to relate the <input>
and <label>
. We use the sibling selector (~
) for all our <input>
states, like :checked
or :disabled
. When combined with the .form-check-label
class, we can easily style the text for each item based on the <input>
's state.
Our checks use custom Bootstrap icons to indicate checked or indeterminate states.
Checks
{{< example >}}
Indeterminate
Checkboxes can utilize the :indeterminate
pseudo class when manually set via JavaScript (there is no available HTML attribute for specifying it).
{{< example class="bd-example-indeterminate">}}
Disabled
Add the disabled
attribute and the associated <label>
s are automatically styled to match with a lighter color to help indicate the input's state.

Radios

Disabled
Add the disabled
attribute and the associated <label>
s are automatically styled to match with a lighter color to help indicate the input's state.

Switches
A switch has the markup of a custom checkbox but uses the .form-switch
class to render a toggle switch. Switches also support the disabled
attribute.

Default (stacked)
By default, any number of checkboxes and radios that are immediate sibling will be vertically stacked and appropriately spaced with .form-check
.

Inline
Group checkboxes or radios on the same horizontal row by adding .form-check-inline
to any .form-check
.

Without labels
Omit the wrapping .form-check
for checkboxes and radios that have no label text. Remember to still provide some form of label for assistive technologies (for instance, using aria-label
).

Toggle buttons
Checkbox toggle buttons
Bootstrap's .btn
styles can be applied to <label>
s, to provide checkbox style button toggling. Add an input with a .btn-check
class as previous sibling to toggle the input state.
{{< example >}} {{< /example >}}
{{< example >}} {{< /example >}}
Radio toggle buttons
Toggle buttons can be grouped in a [button group]({{< docsref "/components/button-group" >}}) if needed.
