Example 6: bootstrap grid

<!----------------------- BOOTSTRAP GRID SYSTEM ------------------------>

This code will create 4 boxes placed side by side, which will be 
dynamically positioned, according to the size of the screen. We define 
the following behavior: 


<!-- Desktop Display: we have 4 columns per row (each occupies 3 units out of 12)  -->

class = "col-lg-3"   <!-- display large with 12/3 = 4 columns -->


<!-- Tablet Display: we have 3 columns per row (each occupies 4 units out of 12)  -->

class = "col-md-4"   <!-- display medium with 12/4 = 3 columns -->


<!-- Mobile Display: we have 2 columns per row (each occupies the 6 units of 12)  -->

class = "col-sm-6"  <!-- display small with 12/6 = 2 columns -->
