 For more structured form layouts that are also responsive, you can utilize Bootstrap's [predefined grid classes](/layout/grid/#predefined-classes) or [mixins](/layout/grid/#sass-mixins) to create horizontal forms. Add the `.row` class to form groups and use the `.col-*-*` classes to specify the width of your labels and controls.
 
-Be sure to add `.form-control-label` to your `<label>`s as well so they're vertically centered with their associated form controls. For `<legend>` elements, you can use `.form-control-legend` to make them appear similar to regular `<label>` elements.

 Bootstrap includes validation styles for danger, warning, and success states on form controls. Here's a rundown of how they work:
 
-- To use, add `.has-warning`, `.has-danger`, or `.has-success` to the parent element. Any `.form-control-label`, `.form-control`, or custom form element will receive the validation styles.
+- To use, add `.has-warning`, `.has-danger`, or `.has-success` to the parent element. Any `.col-form-label`, `.form-control`, or custom form element will receive the validation styles.
 - Contextual validation text, in addition to your usual form field help text, can be added with the use of `.form-control-feedback`. This text will adapt to the parent `.has-*` class. By default it only includes a bit of `margin` for spacing and a modified `color` for each state.
 - Validation icons are `url()`s configured via Sass variables that are applied to `background-image` declarations for each state.
 - You may use your own base64 PNGs or SVGs by updating the Sass variables and recompiling.
