+### Use `:is` for Selecting Mulitple Elements
+
+If you have multiple selectors, and you want to give same css, you can use this pseudo-class. The `:is()` function takes precedence over other selectors, so you can use it to override styles set by other selectors.
+
+```css
+.highlights {
+  background-color: blue;
+}
+
+:is(.highlights) {
+  background-color: yellow;
+  font-weight: bold;
+}
+```
+
+Morever you can use the `:is()` function to select multiple elements at once, by combining selectors in the parentheses. For example: `:is(h1, p)` will select all elements with either the tags `"h1"` or the `"p"`.
