 ## About
 
-Placeholders can be used to enhance the experience of your application. They're built only with HTML and CSS, meaning you don't need any JavaScript to create them. You will, however, need some custom JavaScript to toggle their visibility. Their appearance, color, and sizing can be easily customized with our utility classes.

 ## How it works
 
-Create placeholders with the `.placeholder` class and a grid column class (e.g., `.col-6`) to set the `width`. They can replace the text inside an element or be added as a modifier class to an existing component.
+Create placeholders using the `.placeholder` class along with a grid column class (e.g., `.col-6`) to define the `width`. These placeholders can either replace text inside an element or be added as a modifier class to an existing component.
+
+To ensure the `height` is maintained, we style `.btn`s with `::before`. This pattern can be expanded for other cases or a `&nbsp;` can be added inside the element to match the height when actual text appears.
 
-We apply additional styling to `.btn`s via `::before` to ensure the `height` is respected. You may extend this pattern for other situations as needed, or add a `&nbsp;` within the element to reflect the height when actual text is rendered in its place.

-The use of `aria-hidden="true"` only indicates that the element should be hidden to screen readers. The *loading* behavior of the placeholder depends on how authors will actually use the placeholder styles, how they plan to update things, etc. Some JavaScript code may be needed to *swap* the state of the placeholder and inform AT users of the update.
+Using `aria-hidden="true"` simply tells screen readers to ignore the element. The actual *loading* behavior of the placeholder depends on how authors implement and style the placeholder, as well as how they update it. Some JavaScript may be necessary to *toggle* the placeholder's state and notify AT users of the change.
