The List View adds a default item separator (border-bottom), and using lv-col helpers can make it visible under images. There can also be an inline-image baseline gap.
Fix options:
Remove separator:
.mx-listview .mx-listview-item { border-bottom: none; }Remove inline gap:
.mx-image, .mx-image img { display: block; }Or set on the column: .lv-col-md-1 { line-height: 0; } and reset line-height for text children.
Or: .mx-image img { vertical-align: middle; }
Start with removing the List View item border; if the line persists, set the image to display: block.
Try this I hope it helps
