Hi There,
Just to clarify, you’re using the given CSS code not the JavaScript, right? Please wrap the CSS code on an @media query.
@media (min-width: 768px) {
.x-colophon.top .x-container.max.width .x-column:nth-child(1) {
width: 22%;
}
.x-colophon.top .x-container.max.width .x-column:nth-child(2) {
width: 22%;
}
.x-colophon.top .x-container.max.width .x-column:nth-child(3) {
width: 48%;
}
}
Hope it helps, Cheers!
