-Bootstrap normalizes common HTML5 form elements and adds a number of layout options for building forms of all sizes.
+Bootstrap provides several form control styles, layout options, and custom components for creating a wide variety of forms.
 
-## Example form
+## Form controls
 
-Individual form controls automatically receive some global styling. All textual `<input>`, `<textarea>`, and `<select>` elements with `.form-control` are set to `width: 100%;` by default. Wrap labels and controls in `.form-group` for optimum spacing.
+Bootstrap's form controls expand on [our Rebooted form styles](/components/reboot/#forms) with classes. Use these classes to opt into their customized displays for a more consistent rendering across browsers and devices. The example form below demonstrates common HTML form elements that receive updated styles from Bootstrap with additional classes.
 
-**Do not mix form groups directly with [input groups](/components/#input-groups).** Instead, nest the input group inside of the form group.
+Remember, since Bootstrap utilizies the HTML5 doctype, **all inputs must have a `type` attribute** for proper rendering.

+## Form layouts
+
+Since Bootstrap applies `display: block` and `width: 100%` to almost all our form controls, forms will by default stack vertically. Additional classes can be used to vary this layout on a per-form basis.
+
+### Form groups
+
+The `.form-group` class is the easiest way to add some structure to forms. It's only purpose is to provide `margin-bottom` around a label and control pairing. As a bonus, since it's a class you can use it with `<fieldset>`s, `<div>`s, or nearly any other element.
 
-Add `.form-inline` to your `<form>` or a parent element for left-aligned and inline-block controls. Inputs and selects are set to `width: auto;` in inline forms. Depending on your layout, additional custom widths may be required. As shown below, you should alwys include a `<label>` with each form control.
+{% example html %}
+<form>
+  <fieldset class="form-group">
+    <label for="formGroupExampleLabel">Example label</label>
+    <input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input">
+  </fieldset>
+  <fieldset class="form-group">
+    <label for="formGroupExampleLabel2">Another label</label>
+    <input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input">
+  </fieldset>
+</form>
+{% endexample %}
+
+### Inline forms
+
+Use the `.inline-form` class to to display a series of labels, form controls, and buttons on a single horizontal row. Form controls within inline forms behave differently:
+
+- Controls are `display: inline-block` to provide alignment control via `vertical-align` and `margin`.
+- Controls receive `width: auto` to override the Bootstrap default `width: 100%`.
+- Controls **only appear inline in viewports that are at least 768px wide** to account for narrow viewports on mobile devices.
 
-**Inline forms only appear inline in viewports that are at least 768px wide.**
+Because of this, you may need to manually adddres the width and alignment of individual form controls. Lastly, as shown below, you should always include a `<label>` with each form control.

-## Horizontal forms
+### Using the Grid
 
-Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding `.form-horizontal` to the form or form control's parent. Doing so changes `.form-group`s to behave as grid rows, so no need for `.row`.
+For more structured form layouts, you can utilize Bootstrap's predefined grid classes (or mixins). Add the `.row` class to form groups and use the `.col-*` classes to specify the width of your labels and controls.

+## Checkboxes and radios
 
 Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.
 
 A checkbox or radio with the `disabled` attribute will be styled appropriately. To have the `<label>` for the checkbox or radio also display a "not-allowed" cursor when the user hovers over the label, add the `.disabled` class to your `.radio`, `.radio-inline`, `.checkbox`, `.checkbox-inline`, or `<fieldset>`.
