This website is powered by Jekyll and uses some Bootstrap and Bootswatch. We tried to make it simple yet adaptable, so that it is easy for you to re-use it for your purpose.
All pages are written in markdown for easy editing, and Jekyll uses Liquid for the data-driven pages. The publicaion list, news items, and group members are stored as .yml data sheets (plain text) in the _data folder, so that one can update the website easily. The pages are in the _pages folder. Updating and maintaining is easy using Github (not worldpress-easy, but there are other advantages (see e.g. this, or this). Jekyll takes all the markdown and data files, and creates beautiful html files in the _site folder.
If you never used Jekyll, read the wikipedia article article and check out their website. Same for Github, which will host your first website draft.
