The task is simply implementing the product detail page for a product. However, product detail page has a lot of subpages such as initiatives, challenges, prouduct tree etc. The task is to implement each page according to the ux-prototype repository (https://github.com/OpenUnited/ux-prototype). The HTML files are prefixed with 'product_'. Every page that has 'product_' prefix needs to implemented under the product detail page. The task is big. Therefore, it is advised to be completed in multiple pull requests.
