The border-collapse CSS property sets whether cells inside a <table> have shared or separate borders.

When cells are collapsed, the border-style value of inset behaves like groove, and outset behaves like ridge.

When cells are separated, the distance between cells is defined by the border-spacing property.

Syntax

/* Keyword values */
border-collapse: collapse;
border-collapse: separate;

/* Global values */
border-collapse: inherit;
border-collapse: initial;
border-collapse: unset;

The border-collapse property is specified as a single keyword, which may be chosen from the list below.

Values

collapse
Adjacent cells have shared borders (the collapsed-border table rendering model).
separate
Adjacent cells have distinct borders (the separated-border table rendering model).

Formal syntax

collapse | separate
