Requirements (see attached image first) : 1. Re-design the area I marked with a blue border. That's all, simple and straight forward. BUT, things you need to know : 1. The new design should have the exact same height / width. 2. You won't touch any code, just provide me the new designed images. 3. I will provide you the icons for the navigation bar. 3. Submit your portfolio after bidding. **We are looking for a clean, simplistic yet outstanding design & color scheme for the navigation bar.**
