+#### Style search results
+
+The `::search-text` pseudo-element allows you to style the portions of text that match a user's search query when the user searches within a page by using **Ctrl+F** or **Command+F**.
+
+The pseudo-element can be combined with the `:current` pseudo-class to style the currently highlighted search result differently from the other search results.

+#### Overscroll effect on nested scroll containers
+
+On platforms which support the overscroll effect where users can scroll the page beyond the start or end of the content, such as on mobile devices, Microsoft Edge now applies this effect to nested scroll containers as well.
+
+You remain in control of the overscroll behavior by using the `overscroll-behavior` CSS property.
