Not sure what he meant by “duplicate tables”. But those 4 posts can be made to be displayed as 2 posts per line.
In expound.css
Find:
.featured-content-secondary article {
margin-left: 10px;
margin-right: 10px;
width: 220px;
float: left;
}
Replace with:
.featured-content-secondary article {
margin-left: 40px;
margin-right: 40px;
width: 440px;
float: left;
}
Its much better if you make a child them to do this so that custom edits are preserved after theme update.
/*
Theme Name: Expound Child
Template: expound
*/
@import url("../expound/style.css");
/* =Theme customization starts here
-------------------------------------------------------------- */
.featured-content-secondary article {
margin-left: 40px;
margin-right: 40px;
width: 440px;
float: left;
}
