@@ -71,6 +71,24 @@ You can see this in action with a live demo:
 When an alert is dismissed, the element is completely removed from the page structure. If a keyboard user dismisses the alert using the close button, their focus will suddenly be lost and, depending on the browser, reset to the start of the page/document. For this reason, we recommend including additional JavaScript that listens for the `closed.bs.alert` event and programmatically sets `focus()` to the most appropriate location in the page. If you're planning to move focus to a non-interactive element that normally does not receive focus, make sure to add `tabindex="-1"` to the element.

 When you do this, we recommend including additional JavaScript to move the focus programmatically to the container when it is opened. Otherwise, keyboard users and users of assistive technologies will likely have a hard time finding the newly revealed content - particularly if the container that was opened comes *before* the toggler in the document's structure. We also recommend making sure that the toggler has the `aria-controls` attribute, pointing to the `id` of the content container. In theory, this allows assistive technology users to jump directly from the toggler to the container it controls–but support for this is currently quite patchy.

+
+### Customizing
+
+Validation states can be customized via Sass with the `$form-validation-states` map. Located in our `_variables.scss` file, this Sass map is how we generate the default `valid`/`invalid` validation states. Included is a nested map for customizing each state's color, icon, tooltip color, and focus shadow. While no other states are supported by browsers, those using custom styles can easily add more complex form feedback.

-## Sass
-
-Bootstrap uses [Dart Sass](https://sass-lang.com/dart-sass) for compiling our Sass source files into CSS files (included in our build process), and we recommend you do the same if you're compiling Sass using your own asset pipeline. We previously used Node Sass for Bootstrap v4, but LibSass and packages built on top of it, including Node Sass, are now [deprecated](https://sass-lang.com/blog/libsass-is-deprecated).
-
-Dart Sass uses a rounding precision of 10 and for efficiency reasons does not allow adjustment of this value. We don't lower this precision during further processing of our generated CSS, such as during minification, but if you chose to do so we recommend maintaining a precision of at least 6 to prevent issues with browser rounding.
-
 ## Autoprefixer
 
 Bootstrap uses [Autoprefixer][autoprefixer] (included in our build process) to automatically add vendor prefixes to some CSS properties at build time. Doing so saves us time and code by allowing us to write key parts of our CSS a single time while eliminating the need for vendor mixins like those found in v3.

-### LTR and RTL at the same time
-
-Need both LTR and RTL on the same page? Thanks to [RTLCSS String Maps](https://rtlcss.com/learn/usage-guide/string-map/), this is pretty straightforward. Wrap your `@import`s with a class, and set a custom rename rule for RTLCSS:
-
-```scss
-/* rtl:begin:options: {
-  "autoRename": true,
-  "stringMap":[
-    "name": "ltr-rtl",
-    "priority": 100,
-    "search": ["ltr"],
-    "replace": ["rtl"],
-    "options": {
-      "scope": "*",
-      "ignoreCase": false
-    }
-  ]
-} */
-.ltr {
-  @import "../node_modules/bootstrap/scss/bootstrap";
-}
-/*rtl:end:options*/
-```
-
-After running Sass then RTLCSS, each selector in your CSS files will be prepended by `.ltr`, and `.rtl` for RTL files. Now you're able to use both files on the same page, and simply use `.ltr` or `.rtl` on your components wrappers to use one or the other direction.
-
-{{< callout warning >}}
-#### Edge cases and known limitations
-
-While this approach is understandable, please pay attention to the following:
-
-1. When switching `.ltr` and `.rtl`, make sure you add `dir` and `lang` attributes accordingly.
-2. Loading both files can be a real performance bottleneck: consider some [optimization]({{< docsref "/customize/optimize" >}}), and maybe try to [load one of those files asynchronously](https://www.filamentgroup.com/lab/load-css-simpler/).
-3. Nesting styles this way will prevent our `form-validation-state()` mixin from working as intended, thus require you tweak it a bit by yourself. [See #31223](https://github.com/twbs/bootstrap/issues/31223).
