Can I customize particular pages that are powered by Tagalys to be changed from a grid of 4 to a grid of 3?

This can be done by adding the following CSS for the desired pages. 


@media only screen and (min-width: 900px) {
html .tagalys-namespace .tagalys-product-tile, html #tagalys-namespace .tagalys-product-tile {
width: 33%;
}

}
@media only screen and (min-width: 1200px)
{
html .tagalys-namespace .tagalys-product-tile, html #tagalys-namespace .tagalys-product-tile
{
width: 33%;
}
}
