How to Select Specific Columns in a Table Using CSS `nth-child` Selectors?

CSS Selectors for nth Range

To select specific columns in a table, utilize the nth-child CSS selector. The provided selector, '.myTableRow td:nth-child(?)', targets table data cells (td) based on their position in the parent table row. However, the question mark placeholder needs replacing with a range.

nth-Child Range Selection

To select columns 2 through 4, employ either of these approaches:

Option 1:

<code class="css">.myTableRow td:nth-child(n+2):nth-child(-n+4){
  background-color: #FFFFCC;
}</code>

This syntax ensures selection of cells starting from the 2nd position (n 2) and up to the 4th position (-n 4).

Option 2 (Clearer Syntax):

<code class="css">.myTableRow td:nth-child(2):nth-child(4){
  background-color: #FFFFCC;
}</code>

This alternative provides a more explicit range specification, explicitly identifying columns 2 and 4. It eliminates the need to calculate the total number of columns.

nth-Child Syntax Explanation:

  • ':nth-child(n X)' targets elements from the 'Xth' position onward.
  • ':nth-child(-n X)' targets elements up to the 'Xth' position.

Example:

Consider the following HTML:

<code class="html"><table class="myTable">
  <tr>
    <td>Item 1</td>
    <td>Item 2</td>
    <td>Item 3</td>
  </tr>
</table></code>

Applying the selector '.myTable tr:nth-child(2)' would highlight the second row in the table.

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
