Thierry: I am commeting off the use of <button class="btn btn-danger">SensLabMap</button> which,
 although rudimentarily ported to the django framework, 
causes a weird behaviour especially wrt scrolling. 
On my Mac <button class="btn btn-warning"> I cannot use the mouse to scroll</button> any longer
if I keep this active, so for now it's disabled
