customizing grid (color)

[Vlad]

Is there a way to customize colors in the w2p grid similar to bootstrap idea, for example something like .table_dark in bootstrap? 

I tried this: 

<style>
.w2p_odd {
   background-color: brown;
   color:white;
}
.w2p_even {
   background-color: black;
   color:white;
}
</style>

and it gives weird results. wondering what's the most appropriate way there is for this kind of customization.
