 ## CSS
 
+### Variables
+
+{{< added-in "5.3.0" >}}
+
+As part of Bootstrap's evolving CSS variables approach, forms now use local CSS variables for validation for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.
+
+{{< scss-docs name="root-form-validation-variables" file="scss/_root.scss" >}}
+
+These variables are also color mode adaptive, meaning they change color while in dark mode.
+
 ### Sass variables
 
 {{< scss-docs name="form-feedback-variables" file="scss/_variables.scss" >}}
 
+{{< scss-docs name="form-validation-colors" file="scss/_variables.scss" >}}

 ### Sass mixins
 
 Two mixins are combined together, through our [loop](#loop), to generate our form validation feedback styles.
