It's work just like Twitter Bootstrap, but more configurable.

It's pretty simple to use, choose the number of column and give them the right class :

<div class="container">
    <div class="row">
        <div class="col-3"></div>
        <div class="col-3"></div>
        <div class="col-3"></div>
        <div class="col-3 last"></div>
    </div>
    <div class="row">
        <div class="col-3"></div>
        <div class="col-2 offset-4"></div>
        <div class="col-3 last"></div>
    </div>
</div>

.container is the block who content all your rows
.row is just like his name, he contains the column of your layout
.col-1 or .offset-1 = one column
.last is the required class for the last column

With @columnNumber you can choose how much columns your Grid had !
You can choose the max-width of your grid with @maxWidth
And @columnRatio define the proportion between column and gutter !

This fiews parameters can completly change the look of your Grid. The LESS file is very easy to use, so don't be afraid and choose how is your Grid !
