Column combinator

Experimental:This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The column combinator (||) is placed between two CSS selectors. It matches only those elements matched by the second selector that belong to the column elements matched by the first.

css
/* Table cells that belong to the "selected" column */ col.selected||td { background: gray; }

Syntax

css
/* The white space around the || combinator is optional but recommended. */ column-selector || cell-selector { /* style properties */ }
