Method 1: Using the Theme Customization Tool
One of the easiest and most traditional ways to Customize WordPress Themes is by using the built-in Theme Customization Tool available inside the WordPress dashboard. This tool allows users to make visual changes to their website without touching complex code files. You can usually access it by navigating to Appearance > Customize from the WordPress admin panel. However, many users become confused when they cannot find this option in their dashboard. This happens because newer versions of WordPress work differently depending on the type of theme you are using.
If your website runs on WordPress version 5.9 or higher and you are using a block-based theme such as Twenty Twenty-Three, the traditional customization tool may no longer appear. Instead, WordPress replaces it with the newer Site Editor. In such cases, the “Appearance” menu will only display options like “Themes” and “Editor.” This change happened because WordPress introduced Full Site Editing (FSE), making the old customization interface less necessary for block themes.
However, the Theme Customizer still works perfectly with classic themes such as Astra or Twenty Twenty-One. If you activate a classic theme on a newer WordPress version like 6.3, you will again see the “Customize” option under the Appearance section. This tool remains popular because it offers a simple and beginner-friendly way to customize WordPress Themes while preserving website stability and compatibility during updates.
The professional WordPress themes Customizer provides several useful options for improving website appearance and performance. Depending on your active theme, you may be able to:
- Change typography settings such as font style, size, and weight
- Modify color palettes and background settings
- Upload a logo and favicon
- Create and edit navigation menus
- Customize homepage layouts
- Configure blog settings
- Edit footer sections and copyright text
- Add additional CSS code for advanced styling
Premium themes usually provide more customization options than default WordPress themes. One of the biggest advantages of this method is the real-time preview feature. Any changes you make appear instantly on the right side of the screen, allowing you to see the results before publishing them live.
To edit a section, simply click on the blue pencil icon visible on different parts of the page. This opens the corresponding settings menu in the left sidebar. Once all changes are completed, click the “Publish” button to save them permanently. Since modifications are stored within the theme settings, they usually remain safe during WordPress updates.
For beginners who want to Customize WordPress Themes quickly and safely without advanced coding knowledge, the Theme Customization Tool remains one of the most reliable methods available.
Method 2: Using the WordPress Site Editor
The second modern way to Customize WordPress Themes is through the WordPress Site Editor, introduced with Full Site Editing support in WordPress 5.9. This feature represents a major shift in how websites are designed and managed inside WordPress. Unlike the older customization tool, the Site Editor gives users complete control over almost every part of the website using blocks.
To access the Site Editor, your website must meet two conditions:
You must use WordPress version 5.9 or higher
You must activate a block-based theme
Once a compatible theme like Neve FSE is installed and activated, the “Appearance” menu changes and becomes simpler. Instead of multiple submenu items, you will mainly see “Themes” and “Editor.” Clicking on Appearance > Editor opens the Site Editor interface.
The Site Editor allows users to Customize WordPress Themes in a much more advanced and flexible way compared to the traditional Customizer. With this tool, you can modify almost every section of the website, including:
- Headers and footers
- Blog templates
- Homepage layouts
- Archive pages
- Search result pages
- 404 error pages
- Navigation menus
- Global color palettes
- Typography settings
- Widget areas
- Block patterns and reusable templates
Unlike the older customization interface, all editing takes place directly on the screen using blocks. This creates a best WordPress page builder like experience where users can visually edit layouts in real time. For example, you can click on a button block to change its text, replace images instantly, adjust spacing, or modify colors without editing code manually.
The block insertion tool makes it easy to add new content elements such as galleries, buttons, testimonials, videos, columns, and banners. Each block also includes individual settings for typography, colors, alignment, dimensions, and responsiveness. This gives users much greater creative freedom when they Customize WordPress Themes using the Site Editor.
Another major advantage of the Site Editor is the ability to configure global styles. Instead of editing each page separately, users can apply a consistent color palette, typography style, and spacing system across the entire website. This helps maintain branding consistency while improving user experience and design quality.
However, despite its flexibility, the Site Editor still has a learning curve. Because it relies heavily on blocks, templates, and layout structures, beginners may initially find it more technical than the older Theme Customizer. Building professional layouts often requires a good understanding of web design principles and content structuring.
For users who want complete control over design and layout customization without depending heavily on third-party page builders, the Site Editor offers a powerful solution. As WordPress continues to evolve, this modern approach will likely become the primary way to Customize WordPress Themes in future website development workflows.
