How can CSS be utilized for color changes in tables without using IDs for each row or cell in PHP?

To change the color of rows or cells in a table without using IDs for each element, you can utilize the :nth-child() pseudo-class selector in CSS. This selector allows you to target specific elements based on their position within a parent element. By using this selector in conjunction with CSS classes or inline styles, you can easily apply different colors to alternating rows or cells in a table. 

<table>
    <tr class="odd">
        <td>Row 1, Cell 1</td>
        <td>Row 1, Cell 2</td>
    </tr>
    <tr class="even">
        <td>Row 2, Cell 1</td>
        <td>Row 2, Cell 2</td>
    </tr>
    <tr class="odd">
        <td>Row 3, Cell 1</td>
        <td>Row 3, Cell 2</td>
    </tr>
</table>

<style>
    tr:nth-child(odd) {
        background-color: lightblue;
    }

    tr:nth-child(even) {
        background-color: lightgreen;
    }
</style>
