The grid need to use percent and compute the nearest number for the columns

[lenybernard]

For example, if we set this:

{{ almanach_grid([
        almanach_gridItem('Div Grid Item 1', {
            classGridItem: {
                sm: 75,
                lg: 50
            }
        }),
        almanach_gridItem('Div Grid Item 2', {
            classGridItem: {
                sm: 25,
                lg: 50
            }
        })
    ])
}}

should render in bootstrap:

<div class="row">
    <div class="col-sm-8 col-lg-6"></div>
    <div class="col-sm-4 col-lg-6"></div>
</div>

Beware the possibilty with sass to change the max number of columns on one line. It is indeed by default 12, but it can be changed.
