WordPress Sub Theme is a tool to customize the appearance and functionality of the theme, reducing the risk of modifying the parent theme. The main steps include: creating a child theme directory, creating a stylesheet file, importing the parent theme stylesheet in it, adding custom CSS, saving changes and activate the child theme. Advantages of using sub-topics include: security, flexibility, update compatibility, and portability.
Use of WordPress sub-themes
WordPress subthemes are a powerful tool for customizing the appearance and functionality of the theme. It allows you to modify the parent theme without directly editing the original theme file, reducing the risk of destroying the theme.
How to use WordPress subthemes
To use WordPress subthemes, follow these steps:
- Create a child theme directory: Create a new directory under the
/wp-content/themesdirectory of the WordPress installation directory and name it your child theme name (such asmy-child-theme). - Create a stylesheet file: Create a file named
style.cssin the child theme directory and add the following code:
<code class="css">/* Theme Name: My Child Theme Theme URI: https://example.com/my-child-theme/ Description: A child theme for the Twenty Twenty-One theme. Author: John Doe Version: 1.0.0 */ @import url("../twentytwentyone/style.css");</code>
This code declares the metadata for the child topic and imports the stylesheet from the parent topic (in this case Twenty Twenty-One).
- Custom styles: You can add custom CSS to the
style.cssfile to overwrite or extend the style of the parent theme. For example, to change the header color, you can add the following code:
<code class="css">.site-header { background-color: #000000; }</code>
- Save changes: Save the
style.cssfile and access the WordPress admin area. - Activate a child theme: Navigate to Appearance > Themes and select and activate your child theme.
Advantages
There are many advantages to using WordPress subthemes:
- Safety: Sub-themes prevent you from breaking the parent theme even if you make unexpected changes.
- Flexibility: You can easily customize the style and functionality of your theme without touching the parent theme file.
- Update Compatibility: When the parent theme is updated, the child theme is not overwritten, so your customization is not lost.
- Portability: Sub-themes can be easily migrated from one WordPress site to another.

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.
