Blog Post Display on Home Page – Grid Setup

Select the looper block, set its display to grid, and set grid-template-columns to 1fr 1fr 1fr 1fr

You have a custom selector that set the first post to span 2 columns and 3 rows.

.gb-looper-25cad51b :first-child {
    grid-column: span 2;
    grid-row: span 3;
    height: 80%;
}

Can you select the looper block, click the manage selectors button, check if there is such a selector, if so, delete it.

You are welcome   🙂
