Is there a way to alternate row colors without using CSS? Yes, you can alternate row colors in an HTML table without CSS by using inline styles or JavaScript. This method is useful when you want to style tables dynamically or when CSS is not an option.

How to Alternate Row Colors with Inline Styles?

Using inline styles is a straightforward way to alternate row colors in HTML tables. Here’s how you can achieve this:

<table>
  <tr style="background-color: #f2f2f2;">
    <td>Row 1, Cell 1</td>
    <td>Row 1, Cell 2</td>
  </tr>
  <tr style="background-color: #ffffff;">
    <td>Row 2, Cell 1</td>
    <td>Row 2, Cell 2</td>
  </tr>
  <tr style="background-color: #f2f2f2;">
    <td>Row 3, Cell 1</td>
    <td>Row 3, Cell 2</td>
  </tr>
</table>

Pros and Cons of Using Inline Styles

Inline styles can be beneficial in specific scenarios but also have limitations:

• Pros:

  • Simplicity: Easy to implement for small tables.
  • No CSS Required: Useful when CSS is not available.

• Cons:

  • Repetitive: Can become cumbersome for large tables.
  • Lack of Flexibility: Difficult to maintain and update styles.

How to Alternate Row Colors with JavaScript?

JavaScript provides a dynamic way to alternate row colors, especially for larger tables or when you need more control.

JavaScript Example

Here’s a simple JavaScript code snippet to alternate row colors:

<table id="myTable">
  <tr>
    <td>Row 1, Cell 1</td>
    <td>Row 1, Cell 2</td>
  </tr>
  <tr>
    <td>Row 2, Cell 1</td>
    <td>Row 2, Cell 2</td>
  </tr>
  <tr>
    <td>Row 3, Cell 1</td>
    <td>Row 3, Cell 2</td>
  </tr>
</table>

<script>
  var table = document.getElementById("myTable");
  var rows = table.getElementsByTagName("tr");

  for (var i = 0; i < rows.length; i++) {
    if (i % 2 === 0) {
      rows[i].style.backgroundColor = "#f2f2f2";
    } else {
      rows[i].style.backgroundColor = "#ffffff";
    }
  }
</script>

Benefits of Using JavaScript

• Dynamic Styling: Easily apply styles to large tables.
• Flexibility: Modify styles without altering HTML structure.
