Hello Jesse,
Thanks for writing in!
To resolve your issue, please add the following CSS code in the X > Theme Options > Global CSS (http://prntscr.com/evui3r)
@media (min-width:481px) and (max-width: 979px) {
.x-column.x-md {
float: left;
width: 48%;
margin-right: 4%;
}
.x-column.x-md:nth-child(2n),
.x-column.x-md.last,
.x-column.x-md:last-of-type {
margin-right: 0;
}
}
This custom code will make sure that the 4 column area will collapse into 2 columns between 979 and 481 screen sizes.
We would love to know if this has worked for you. Thank you.
