Column combinator - CSS | MDN
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.
/* Table cells that belong to the "selected" column */
col.selected||td {
background: gray;
}
/* The white space around the || combinator is optional but recommended. */
column-selector || cell-selector {
/* style properties */
}
<table border="1">
<colgroup>
<col span="2" />
<col class="selected" />
</colgroup>
<tbody>
<tr>
<td>A</td>
<td>B</td>
<td>C</td>
</tr>
<tr>
<td colspan="2">D</td>
<td>E</td>
