-for suggested alternatives and patterns.
+Layout for pages is a combination of spacing units between components, and responsive changes based on the available viewport. EDS provides
+configururation to use with tailwind, if desired. At the core, EDS also provides tokens to use, which align with spacing units defined in design.

 However, it's important to be able to control spacing between components, so EDS works well with tailwind utility 
 classes like [margin](https://tailwindcss.com/docs/margin).

+Below, we use one of the size units to demonstrate how to use EDS sizing utility classes (with tokens).

 ```jsx
-<InlineNotification title="lorem ipsum dolor sit amet" className="mb-5" />
+<InlineNotification title="lorem ipsum dolor sit amet" className="mx-size-5" />
 ```

+Just like with [standard tailwind spacing values](https://tailwindcss.com/docs/customizing-spacing), the `size-X` will correspond to those used in design, AND
+be available across all the documented spacing utilities. For now, we provide these along side the built-in utilities, for compatibility.
