Additional CSS
Additional CSS section in the WordPress Customizer allows you to add custom CSS to style your site without modifying theme files.
Here's how to use this feature effectively:

Customizing with Additional CSS:
Accessing Additional CSS:
Go to Appearance > Customize.
Click on the Additional CSS section.
Adding Custom CSS:
In the text area, you can write or paste your custom CSS code.
As you type, you’ll see a live preview of your changes on the right side.
Best Practices:
Target Specific Elements: Use specific selectors to apply styles to particular elements.
Keep It Organized: Add comments to your CSS to make it easier to understand and maintain.
Test Changes: Use browser developer tools to test changes before adding them to the Additional CSS section.
Common Uses:
Overriding default theme styles.
Changing colors, fonts, and sizes.
Adding margins, padding, or borders.
Hiding or showing specific elements.
Example:
To change the background color of your site’s header:
.site-header { background-color: #f4f4f4;}
