Header Nav's seem not to work due to two things :
1/ Underlying anchors' href property doesnt concur with sections' classes 2/ Clicking the section doesn't seem to toggle the anchors
This is all probably caused by a faulty JQuery
manipulation.
Proposed solution :
On nav click, get underlying anchor's href, correct it, and set it as location
