Exercice 1 :

First of all, after implementing the exercice, I added the assignement : I decided to add my name/student number in the menu.

Here is the implementation of the page when you are clicking on the "Théo OLIVER 5999222013" part of the menu.

To do this, I added a new page (Me) and implemented it exctly as the "About" menu was.

Exercice 2 :

To change the implementation of the assignement, I decided to add an element on the other menu : The "About Me part"

Here is again the resul when you are clicking in the "About Me" menu.

Exercice 3:

Again, I implemented the "About Me" part in the top menu. It is the same as the previous one with a different implementation :

Here is the return page when you are clicking in the "About Me" part.
