Checkbox

A checkbox is a square box that allows you to select the displayed option when activated. It is usually associated with form submissions.

Type Default State Disabled
Unchecked
Checked

Usage

Here is an example of a group of checkboxes. Default spacing is added between each .checkbox when there is more than one checkbox.

HTML
<label class="checkbox">
    <input type="checkbox" name="checkbox-example" />
    <span class="checkbox-check" role="presentation" aria-hidden="true"></span>
    <span class="checkbox-text">Checkbox 1</span>
</label>

<label class="checkbox">
    <input type="checkbox" checked name="checkbox-example" />
    <span class="checkbox-check" role="presentation" aria-hidden="true"></span>
    <span class="checkbox-text">Checkbox 2</span>
</label>

Modifiers

Styles

.checkbox-muted can be used with .checkbox to change the checkbox background color.

HTML
<label class="checkbox checkbox-muted">
    <input type="checkbox" checked name="checkbox-muted" />
    <span class="checkbox-check" role="presentation" aria-hidden="true"></span>
    <span class="checkbox-text">Checked</span>
</label>

is-checked can be used with .checkbox-check to create the appearance of a checkbox with a checked state, without having a clickable .checkbox input element.

HTML
<label class="checkbox">
    <span class="checkbox-check is-checked" role="presentation" aria-hidden="true"></span>
    <span class="checkbox-text">Checked</span>
</label>

Sizes

.checkbox-sm/.checkbox-lg can be used to make a checkbox bigger or smaller than the default.

HTML
<label class="checkbox checkbox-sm">
    <input type="checkbox" name="checkbox-size" />
    <span class="checkbox-check" role="presentation" aria-hidden="true"></span>
    <span class="checkbox-text">Checkbox small</span>
</label>
<label class="checkbox">
    <input type="checkbox" name="checkbox-size" />
    <span class="checkbox-check" role="presentation" aria-hidden="true"></span>
    <span class="checkbox-text">Checkbox default</span>
</label>
<label class="checkbox checkbox-lg">
    <input type="checkbox" name="checkbox-size" />
    <span class="checkbox-check" role="presentation" aria-hidden="true"></span>
    <span class="checkbox-text">Checkbox large</span>
</label>

Validation states

We can use .is-invalid to reflect an invalid validation state. Note that the state should also be display to the user in another way, since by itself color is not enough.

State Class Example
Invalid .checkbox .is-invalid
HTML
<label class="checkbox is-invalid">
    <input type="checkbox" name="checkbox-validation-demo" />
    <span class="checkbox-check" role="presentation" aria-hidden="true"></span>
    <span class="checkbox-text">Checkbox</span>
</label>
