You can find the source in this repo. If you wish to see sample websites from the past we made using this template, you can see Cross-Task Consistency, Taskonomy, Navigation Mid-Level Vision. Feel free to use it for yours!
It should be github.io friendly (see https://epfl-vilab.github.io/project_website_template/). The repo initializes with Cross-Task Consistency website (without the live demos).
