Hi, I have updated my test site to 1.1.1 and it seems to be working fine. http://solsticeorganics.com.au
I would like to increase the width of the three columns by an equal amount of 20px, increasing the overall width by 60px. I have tried altering the css below but it does not seem to have any effect. What is the correct way to change the column and overall site widths?

stylesheet.css
/* fixed colum left + content + right*/
@media (min-width: 768px) {
#column-left .product-layout .col-md-3 {
width: 100%;
}
#column-left + #content .product-layout .col-md-3 {
width: 50%;
}
#column-left + #content + #column-right .product-layout .col-md-3{
width: 100%;
}
#content + #column-right .product-layout .col-md-3{
width: 100%;
}

Thanks,

Andrew
