border-block-color
Sets the color of the borders in the block dimension (top and bottom in horizontal text). It's a logical way to style both 'vertical' ends of a box at once.
Quick example
.sidebar-item {
/* Sets both top and bottom borders to purple */
border-block-color: #7c3aed;
border-block-style: solid;
border-block-width: 2px;
