Looking good, @estelle. A few bits for you to consider, but nothing major.

| ## Custom highlight API in action | ||
|
|
||
| To enable styling text ranges on a webpage using the CSS Custom Highlight API, you create a {{domxref("Range")}} object, then a {{domxref("Highlight")}} object for the range. After registering the highlight using the {{domxref("HighlightRegistry.set()")}} method, you can then select the range using the {{cssxref("::highlight", "::highlight()")}} pseudo-element. The name defined in the `set()` method is used as the parameter of the `::highlight()` pseudo-element selector to select that range.The range selected by the `::highlight()` pseudo-element can be styled using a limited number of properties. |
