Form act as a container for form elements. Form controls automatically receive some global styling with Bootstrap. All textual input, textarea, and select elements with class .form-control have a width of 100%.

• Wrap labels and form controls in div class=”form-group.
• Add class .form-control to all textual input, textarea, and select elements.

    </div>
    <div class="form-check">
      <label class="form-check-label">
        <input class="form-check-input" type="checkbox" name="remember"> Remember me
      </label>
    </div>
    <button type="submit" class="btn btn-primary">Login</button>
  </form>
</div>

In bootstrap inline form, all of the elements are inline, left-aligned, and the labels are alongside.

Standard rules for Inline form layouts:
• Wrap labels and form controls in div class=”form-group.
• Add class .form-control to all textual input, textarea, and select elements.
• Add class .form-inline to the form element
