How to change alternative row color and styles in HTML table

What is the alternative row color in the HTML table? alternative rows represent even and odd numbers, if we have two rows, one row represents one color and another row has a different color.

For example, 1,3,5,7 up to n represents one set called odd-numbered row 2,4,6,8 up to n tells an even-numbered row.

In CSS, :nth-child selector represents the even and odd-numbered rows.

nth-child selector selects the nth-child element.

Syntax

:nth-child(number) {
  css declarations;
}

Here is an event odd rules In this example,

The changed background color of a table row to grey for even rows background color changed to white for odd rows.

tr:nth-child(even){
    background-color:#f0f0f0;

}
tr:nth-child(odd){
    background-color:#ffff;

}

Another way is to add class selectors for even and odd rows We have added roweven and rowodd CSS selectors for the tr tag

You can use it to generate these class selectors using javascript or any programming language.

<table style="width:100%">
  <tr>
    <th>Id</th>
    <th>Name</th>
    <th>Salary</th>
  </tr>
  <tr class="rowodd">
    <td>11</td>
    <td>John</td>
    <td>5000</td>
  </tr>
  <tr class="roweven">
    <td>2</td>
    <td>Andrew</td>
    <td>6000</td>
  </tr>
  <tr class="rowodd">
    <td>3</td>
    <td>Eric</td>
    <td>9000</td>
  </tr>
  <tr class="roweven">
    <td>4</td>
    <td>Mark</td>
    <td>10000</td>
  </tr>
  <tr class="rowodd">
    <td>5</td>
    <td>Jain</td>
    <td>4000</td>
  </tr>
</table>

And css styles

.rowodd{
    background-color:#ffff;
    }
.roweven{
    background-color:#f0f0f0;
    }

It is a Legacy and old way of doing this.

You can use nth-child pseudo-selectors and It supports all the latest browsers.
