Column combinator - CSS: Cascading Style Sheets 编辑

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.

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

Syntax

column-selector || cell-selector {
  /* style properties */
}

Examples

HTML

<table border="1">
  <colgroup>
    <col span="2"/>
    <col class="selected"/>
  </colgroup>
  <tbody>
    <tr>
      <td>A
      <td>B
      <td>C
    </tr>
    <tr>
      <td colspan="2">D</td>
      <td>E</td>
    </tr>
