+Later sources override earlier ones.

+
+Create `layouts/my-layout.vue`:
+
+```vue
+<template>
+  <div class="slidev-layout my-layout">
+    <slot />
+  </div>
+</template>
+
+<style scoped>
+.my-layout {
+  display: flex;

+  justify-content: center;
+}
+</style>
+```
+
+With named slots:
+
+```vue
+<template>
+  <div class="slidev-layout two-areas">
+    <div class="top">
+      <slot name="top" />
+    </div>
+    <div class="bottom">

+  </div>
+</template>
+```
+
+Usage:
