+
+# Code Block Max Height
+
+Set a fixed height for code blocks with scrolling.
+
+## Usage
+
+````md
+```ts {2|3|7|12}{maxHeight:'100px'}
+function add(
+  a: Ref<number> | number,
+  b: Ref<number> | number
+) {
+  return computed(() => unref(a) + unref(b))
+}
+/// ...as many lines as you want
+const c = add(1, 2)
+```
+````
+
+## With Line Highlighting Placeholder
+
+Use `{*}` when you only need maxHeight:
+
+````md
+```ts {*}{maxHeight:'100px'}
+// long code here
+```
+````
+
+## Use Case
+
+When code is too long to fit on one slide but you want to show it all with scrolling.
