 Instead of an HTML form, submitting a GET request in this scenario could've also used JavaScript to submit the request to the server, either using the [Fetch API](https://developer.mozilla.org/docs/Web/API/Fetch_API)` or [XMLHttpRequest API](https://developer.mozilla.org/docs/Web/API/XMLHttpRequest). In most cases, JavaScript can be replaced by using Blazor and C# in an interactive component.
 
+## Style `QuickGrid` rows and cells
+
+You can apply table row and cell styles to the rendered `QuickGrid` component with a stylesheet isolated to the `Index` component using *CSS isolation*.
+
+CSS isolation only applies to the component you associate with the format `{COMPONENT NAME}.razor.css`, where the `{COMPONENT NAME}` placeholder is the component name. The filename is `Index.razor.css` to apply the isolated styles to the `Index` component.
+
+To apply changes to a child component, such as the `QuickGrid` component of the `Index` component, use the `::deep` pseudo-element for element styles in the stylesheet. The `::deep` pseudo-element only works with descendant elements, so the `QuickGrid` component must be wrapped with a `<div>` in order to apply the styles to it.
+
+In `Components/Pages/MoviePages/Index.razor`, place `<div>` tags around the `QuickGrid` component:
+
+```diff
++ <div>
+    <QuickGrid ...>
+        ...
+    </QuickGrid>
++ </div>
+```
+
+In the `MoviePages` folder, add a new isolated stylesheet for the `Index` component. Use `::deep` pseudo-elements to make the row height `3em` and vertically-center the table cell content.
+
+`Components/Pages/MoviePages/Index.razor.css`:
+
+```css
+::deep tr {
+    height: 3em;
+}
+
+    ::deep tr > td {
+        vertical-align: middle;
+    }
+```
+
+Blazor rewrites CSS selectors to match the markup rendered by the component. The rewritten CSS styles are bundled and produced as a static asset for you, so you don't need to take further action to apply the styles to the `QuickGrid` component when it's rendered.
