responsive content columns

I'm used to using bootstrap classes for responsive columns in my articles:
<div class="row">
<div class="col-md-4"> </div>...
or
<div class="row">
<div class="span1"> </div>...

Neither of these seem to work in my RockWall template. Is there another class I should be using?

With gavick templates there are no obvious grid systems. If you need one, you would need to declare your own classes. You can use override.css for that purpose.

Thanks, I'll work to add classes.

I would suggest to add another css file with only grid classes.
Also - please take look at wizardry grid system - it is one of the best I have ever seen.

Where can I link my "grids.css" file into the template? I haven't figured out the mapping of all the includes which piece together the GK Framework.
Thanks.

I think I got it:
I found /layouts/blocks/head.php

$this->API->addCSS($this->API->URLtemplate() . '/css/grids.css');

Exactly this way it should be done .
