FAQ

Two ways to write checkbox HTML

Checkbox HTML can be written in two ways:

With input and label as siblings

<div class="bx--form-item">
  <input
    id="bx--checkbox"
    class="bx--checkbox"
    type="checkbox"
    value="green"
    name="checkbox"
  />
  <label for="bx--checkbox" class="bx--checkbox-label">
    Checkbox (input + label)
  </label>
</div>

With label wrapping input

<div class="bx--form-item">
  <label class="bx--checkbox-label">
    <input
      class="bx--checkbox"
      type="checkbox"
      value="yellow"
      name="checkbox"
    />
    Checkbox (label > input)
  </label>
</div>

Note: You no longer need to include a SVG for the checkmark to render.

Fieldset and Legend

As a best practice, groups of checkboxes should make use of <fieldset> and <legend> (see Form for details). This is especially true for forms submitting data.

But, there are exceptions to the rule. For example, Data Tables make use of checkboxes as a way to select rows of data. Checkboxes in this context would represent an entire row of data in its associated table row.
