* Rather than using href="\\host/about/" in page footer, use
href="protocol://host/about/"
* The old footer uses hacks to be staticly on the bottom. To make it
much simpler one solution is to turn it white and use official
Bootstrap code. This leads to less CSS to maintain and better
cross-browser compatibility.
* On re2o about page (/about/) there is some typos such as :
* assocations > associations
* legitlab > le gitlab
* Use Bootstrap navbar-static-top rather than custom CSS.
The result is the same, so we should be better using directly
Bootstrap CSS.
