+# Complete a css exercise with aider and GPT-4
+
+> The user asks aider about the CSS Exercises repo https://github.com/TheOdinProject/css-exercises/tree/main and complete an animation exercise.
+
+---
+#### >  what is this repo?  
+
+Based on the file list provided, it seems like this repository contains a collection of CSS and HTML exercises, solutions, and examples. The exercises cover various topics such as Flexbox, Grid, Animation, Foundations, and Margin & Padding. The repository also includes images and other assets used in the exercises.

+#### >  /add animation/03-dropdown-menu/README.md  
+_Added animation/03-dropdown-menu/README.md to the chat_  
+
+Yes, I see the content of the `animation/03-dropdown-menu/README.md` file. It describes an exercise to add animation to a dropdown menu, creating a bounce illusion when the dropdown expands close to its final end state. The desired outcome is shown in a GIF file, and the hints provided suggest using the `transform-origin` property and adding an intermediate step to the keyframe at-rule to achieve the bounce effect.
+
+Is there any specific change or improvement you would like me to make to this file or any other file in the repository?
+
+
+---
+#### >  can you make the changes suggested in the readme?  
+
+To make the changes suggested in the `animation/03-dropdown-menu/README.md`, I need to see the contents of the following files:
+
+1. `animation/03-dropdown-menu/style.css`
+2. `animation/03-dropdown-menu/script.js`
+
+Please provide the contents of these files so I can suggest the necessary changes.
+
+_animation/03-dropdown-menu/style.css_  
+_animation/03-dropdown-menu/script.js_  
+_Add these files to the chat? y_  
+
+Apologies for the oversight. I see the content of the `animation/03-dropdown-menu/style.css` and `animation/03-dropdown-menu/script.js` files now. I will suggest the necessary changes to add the bounce animation to the dropdown menu.
+
+```css
+animation/03-dropdown-menu/style.css
+<<<<<<< ORIGINAL
+.visible {
+  display: block;
+}
+=======
+.visible {
+  display: block;
+  animation: expand 0.3s ease-out;
+  transform-origin: top;
+}
+
+@keyframes expand {
+  0% {
+    transform: scaleY(0);
+  }
+  80% {
+    transform: scaleY(1.1);
+  }
+  100% {
+    transform: scaleY(1);
+  }
+}
+>>>>>>> UPDATED
+```
+
+These changes add the bounce animation to the dropdown menu by creating a new keyframe animation called `expand`. The `transform-origin` property is set to `top` to make the dropdown menu start transforming from the top. The intermediate step at 80% of the animation creates the bounce illusion.
