CSS中条形表中的悬停时，列和行突出显示

Question

I'm using trick for CSS only highlight of table column on hover from https://css-tricks.com/simple-css-row-column-highlighting/

It's work perfect, but not for striped table via

tr:nth-of-type(odd) {
    background-color: #f0f0f0;
}

Highlighting not apply to upper and bottom cells in rows with background.

See example here: http://jsfiddle.net/615avo4v/

Please, help me fix this issue without JavaScript.

Thanks in advance!

Change the way you set the stripped background.

Use another pseudo element, this time on the first td of the even rows, and aligned horizontally. (and with a lower z-index).

 * { margin: 0; padding: 0; } table { width: 100%; border-spacing: 0; color: #212121; text-align: left; overflow: hidden; } table>tbody>tr>td { padding: 10px; font-size: 14px; position: relative; } table>tbody>tr:hover { padding: 20px; background-color: #ffa !important; } tr:nth-child(even) td:first-child::before { content: ""; position: absolute; background-color: lightgreen; top: 0; left: -5000px; width: 10000px; height: 100%; z-index: -10; } td:hover::after { content: ""; position: absolute; background-color: #ffa; left: 0; top: -5000px; height: 10000px; width: 100%; z-index: -1; } 

  <table> <tr> <td>col1</td> <td>col2</td> <td>col3</td> <td>col4</td> <td>col5</td> <td>col6</td> <td>col7</td> <td>col8</td> </tr> <tr> <td>col1</td> <td>col2</td> <td>col3</td> <td>col4</td> <td>col5</td> <td>col6</td> <td>col7</td> <td>col8</td> </tr> <tr> <td>col1</td> <td>col2</td> <td>col3</td> <td>col4</td> <td>col5</td> <td>col6</td> <td>col7</td> <td>col8</td> </tr> <tr> <td>col1</td> <td>col2</td> <td>col3</td> <td>col4</td> <td>col5</td> <td>col6</td> <td>col7</td> <td>col8</td> </tr> <tr> <td>col1</td> <td>col2</td> <td>col3</td> <td>col4</td> <td>col5</td> <td>col6</td> <td>col7</td> <td>col8</td> </tr> <tr> <td>col1</td> <td>col2</td> <td>col3</td> <td>col4</td> <td>col5</td> <td>col6</td> <td>col7</td> <td>col8</td> </tr> </table>
