-Symfony comes with a default theme (`form_div_layout.html.twig`_ in Twig and
-``FrameworkBundle:Form`` in PHP) that defines each and every fragment needed
-to render every part of a form.
+Symfony comes with four **built-in form themes** that define each and every
+fragment needed to render every part of a form:
+
+* `form_div_layout.html.twig`_, wraps each form field inside a ``<div>`` element.
+* `form_table_layout.html.twig`_, wraps the entire form inside a ``<table>``
+  element and each form field inside a ``<tr>`` element.
+* `bootstrap_3_layout.html.twig`_, wraps each form field inside a ``<div>`` element
+  with the appropriate CSS classes to apply the default `Bootstrap 3 CSS framework`_
+  styles.
+* `bootstrap_3_horizontal_layout.html.twig`_, it's similar to the previous theme,
+  but the CSS classes applied are the ones used to display the forms horizontally
+  (i.e. the label and the widget in the same row).
 
 In the next section you will learn how to customize a theme by overriding
 some or all of its fragments.
