If you have more than one grid on the same page - you can apply different styles to the grids using CSS ID selector.
<style>
#grid1 {height: 200px;}
#grid2 {height: 100px;}
#grid1 .active-column-0 {width: 200px;}
#grid2 .active-column-0 {width: 150px;}
#grid1 .active-column-1 {background-color: threedlightshadow;}
#grid2 .active-column-1 {background-color: infobackground;}
.active-column-2 {text-align: right;}
.active-column-3 {text-align: right;}
.active-column-4 {text-align: right;}
</style>
In this example there are two grids on the page, which are assigned the 'grid1' and 'grid2' IDs using setId(id) function.
var obj1 = new Active.Controls.Grid;
obj1.setId("grid1");
...
var obj2 = new Active.Controls.Grid;
obj2.setId("grid2");
...
