+
+# Navigation Direction Variants
+
+Apply different styles based on navigation direction (forward/backward).
+
+## CSS Classes
+
+```css
+/* Delay only when navigating forward */
+.slidev-nav-go-forward .slidev-vclick-target {
+  transition-delay: 500ms;
+}
+.slidev-nav-go-backward .slidev-vclick-target {
+  transition-delay: 0;
+}
+```
+
+## UnoCSS Variants
+
+Use `forward:` or `backward:` prefix:
+
+```html
+<div v-click class="transition forward:delay-300">Element</div>
+```
+
+Animation is only delayed when navigating forward, not when going back.
+
+## Use Case
+
+Create asymmetric animations where entering a slide feels different from leaving it.
