A Complete Guide to Editing CSS Through WordPress Customizer

WordPress Customizer empowers users to customize their website’s appearance and functionality with ease. One of its powerful features is the ability to edit CSS directly from the Customizer interface. In this tutorial, we’ll walk you through the process of editing CSS through WordPress Customizer, allowing you to make style adjustments and enhance your website’s design without touching your theme files.

Step 1: Accessing WordPress Customizer:

To begin, log in to your WordPress admin dashboard. Navigate to Appearance > Customize. This will launch the WordPress Customizer, displaying a live preview of your website alongside customization options.

Step 2: Navigating to Additional CSS:

Within the WordPress Customizer, look for the “Additional CSS” option. This option is typically located towards the bottom of the customization panel. Click on it to access the CSS customization interface.

Step 3: Adding Custom CSS:

In the “Additional CSS” section, you’ll find a text area where you can add your custom CSS code. Start by typing or pasting your CSS code into this text area. WordPress Customizer provides syntax highlighting and error checking to ensure your CSS is written correctly.

Step 4: Previewing Changes:

As you add or modify CSS code, you’ll see the changes reflected in real-time within the live preview pane of the Customizer. This allows you to experiment with different styles and instantly see how they affect your website’s appearance.

Step 5: Making Selective Changes:

WordPress Customizer allows you to make selective CSS changes by targeting specific elements on your website. Use CSS selectors to target elements such as headers, paragraphs, navigation menus, buttons, and more. For example:

/* Example: Changing the color of all paragraph text */
p {
    color: #333333;

Step 6: Saving Changes:

Once you’re satisfied with your CSS modifications, click the “Publish” button at the top of the Customizer panel to save your changes. Your custom CSS will be applied to your website immediately.

Step 7: Previewing on Different Devices:

WordPress Customizer allows you to preview your website’s appearance on different devices, including desktops, tablets, and mobile phones. Use the device icons at the bottom of the Customizer panel to switch between device views and ensure your CSS changes look great across all screen sizes.

Step 8: Reverting Changes:

If you need to revert any CSS changes, simply navigate back to the “Additional CSS” section in WordPress Customizer and remove or modify the relevant CSS code. Don’t forget to click “Publish” to save your changes.

Step 9: Best Practices:

When editing CSS through WordPress Customizer, it’s essential to follow best practices to ensure a smooth and efficient customization process. Keep your CSS code organized, comment your code for clarity, and test your changes thoroughly across different devices and browsers.


Editing CSS through WordPress Customizer provides a user-friendly way to customize your website’s design without the need for coding knowledge or editing theme files directly.
