Full Site Editing: The Future of WordPress Themes

Posted By Pratima Khanalon in Informations, WordPress ThemesTagged , , , , , ,

WordPress has evolved significantly since its inception, transitioning from a simple blogging platform to a full-fledged content management system (CMS) powering over 43% of all websites. One of the most groundbreaking advancements in recent years is Full Site Editing (FSE), a feature introduced in WordPress 5.9 that revolutionizes how themes are built and customized.

FSE empowers users to edit every part of their website—headers, footers, sidebars, and templates—directly from the Block Editor (Gutenberg). This shift marks a departure from traditional theme development, offering unprecedented flexibility and control.

In this article, we’ll explore what Full Site Editing is, how it works, its benefits, and why it represents the future of WordPress themes.

What is Full Site Editing (FSE)?

Full Site Editing is a WordPress feature that extends the Gutenberg Block Editor beyond posts and pages, allowing users to customize their entire website using blocks. Traditionally, modifying a site’s structure required coding or reliance on theme settings. With FSE, users can:

  • Edit global styles (colors, typography, spacing)
  • Modify templates (headers, footers, archives, single posts)
  • Create custom templates without touching code
  • Use block-based theme components for seamless design

FSE is built on block themes, which rely entirely on blocks for layout and styling instead of PHP templates. This approach aligns with WordPress’s vision of making website building more intuitive and accessible.

How Does Full Site Editing Work?

1. Block Themes

FSE requires a block-enabled theme, such as Twenty Twenty-Two or Twenty Twenty-Three. These themes use HTML files with block markup (instead of PHP) to define templates.

Key components of block themes:

  • templates/ – Contains block-based template files (e.g., single.html, archive.html)
  • parts/ – Houses reusable sections like headers and footers
  • theme.json – Controls global styles and settings

2. The Site Editor

The Site Editor (accessed via Appearance → Editor) is the hub for FSE. Here, users can:

  • Browse and edit templates (e.g., 404, search, blog archive)
  • Customize template parts (headers, footers)
  • Modify global styles (colors, fonts, layouts)

3. Global Styles

WordPress 5.9 introduced Global Styles, allowing users to define site-wide design settings (typography, color palettes, spacing) via theme.json. This ensures consistency across the entire site.

4. Template Editing

Users can edit templates directly in the Block Editor, rearranging sections, adding new blocks, and styling elements without coding.

Benefits of Full Site Editing

  1.  Consistent Design System- With Global Styles, changes to colors, fonts, and s
  2.  No-Code Customization- FSE eliminates the need for custom CSS or PHP modifications, making website design accessible to non-developers.
  3. Faster Workflow- Designers and developers can create and modify templates in real-time without switching between the Customizer and theme files.
  4.  Future-Proof Themes- As WordPress shifts toward block-based editing, traditional themes may become obsolete. Block themes are built for the future.
  5.  Enhanced Flexibility- Users can mix and match templates, create custom layouts, and reuse patterns across different pages.

Challenges of Full Site Editing

While FSE is powerful, it’s still evolving, and some challenges remain:

While FSE is promising, it’s not without its challenges:

  1. Learning Curve:
    Long-time WordPress users and developers used to the Classic Editor or Customizer may need time to adapt.
  2. Limited Block Theme Availability:
    While growing, the library of block themes is still smaller compared to classic themes.
  3. Plugin Compatibility Issues:
    Some older plugins may not fully support FSE, especially those that rely on classic theme hooks.
  4. Performance Concerns for Heavy Sites:
    Overusing blocks or installing too many FSE-specific plugins could affect performance.

The Future of WordPress Themes

FSE is not just a trend; it’s the new direction for WordPress. Here’s what we can expect in the coming years:

  • Increased Block Theme Adoption: Most new themes will be block-based, and classic themes may eventually phase out.
  • Better User Experience: More intuitive editing tools and block patterns will make website building easier than ever.
  • Enhanced Integration with AI and Design Tools: As WordPress evolves, FSE may integrate with AI-powered design suggestions for faster site creation.
  • Page Builders Evolving: Page builders will focus on advanced features as basic site building becomes achievable within WordPress itself.

For theme developers and users, now is the time to embrace FSE and explore block themes for future-proof websites.

The Role of Theme Developers in the FSE Era

If users can build anything they want, are theme companies still relevant? Absolutely—in fact, our role is more important than ever, it just shifts from being gatekeepers to being enablers.

In the FSE world, a great theme company like AcmeThemes will provide:

  • A Solid Design Foundation: We design the beautiful, cohesive starting point. This includes crafting professional color palettes, elegant typography combinations, and well-balanced spacing in the theme’s theme.json file (the heart of a block theme’s design).
  • High-Quality, Custom Block Patterns: This is where we can truly add value. We will provide a rich library of unique, artfully designed patterns that go beyond the basics, allowing you to build stunning, complex layouts effortlessly.
  • Optimized Performance and Code: We ensure the theme is lightweight, fast, and built to the highest standards, so you can focus on your content without worrying about technical debt.
  • Specialized Blocks & Functionality: We can develop custom blocks that provide unique features tailored to specific niches (e.g., a “Recipe” block for a food blog theme or an “Event” block for a business theme).

Full Site Editing (FSE) represents a monumental shift in how we build and customize WordPress websites. It moves beyond simple page editing to give you direct control over your entire site—header, footer, sidebars, and all—using the familiar block-based interface. This evolution, powered by Block Themes, is undeniably the future of WordPress, empowering users with unprecedented design freedom and simplifying the entire customization process.

What is Full Site Editing (FSE)?

Full Site Editing, now often referred to as the Site Editor, is a collection of WordPress features that allows you to edit every part of your website using blocks. Think of it this way: for years, the block editor (Gutenberg) let you build your posts and pages piece by piece, like LEGOs. FSE extends that power to your entire site layout.

Before FSE, changing your site’s header, footer, or the layout of your blog archive required digging into theme options, using a separate Customizer interface, or even writing code. Now, you can do it all in one unified, visual interface. It’s a true “what you see is what you get” (WYSIWYG) experience for your whole website. The core idea is to democratize web design, giving regular users the power that was once reserved for developers.

The Shift from Traditional Themes to Block Themes

This new era required a new kind of theme. The transition from classic themes to Block Themes is the foundational change that makes FSE possible.

Traditional (Classic) Themes

Classic themes rely on a mix of PHP templates (like header.php, footer.php, sidebar.php), functions, and the WordPress Customizer.

  • Structure: The layout was hard-coded into PHP files. To change the structure, you needed to create a child theme and edit the code.
  • Customization: Colors, fonts, and widgets were managed through the Customizer, a separate interface with a limited set of controls defined by the theme developer.
  • Flexibility: While powerful, this approach created a disconnect. You edited your content in one place and tweaked your site’s appearance in another, often without a live, one-to-one preview.

Block Themes

Block Themes are built entirely for the Full Site Editing experience. They are fundamentally different.

  • Structure: Instead of PHP templates, they use HTML files that contain block markup. This means the entire theme structure—from the header to the 404 page—is composed of blocks.
  • Customization: All customization happens directly in the Site Editor. There’s no separate Customizer panel. You click on the header, and you edit the header. You want to change the layout of your blog posts? You edit the “Single Post” template directly.
  • Flexibility: This offers near-limitless flexibility. You can visually rearrange elements, add new blocks anywhere, and see the changes happen live.

Key Features of Full Site Editing

FSE isn’t just one feature; it’s a suite of tools working together. Here are the core components you’ll interact with.

The Site Editor

This is your new command center. Accessible viaAppearance > Editor, the Site Editor is the visual canvas where you design your site. Within it, you can access and modify:

  • Templates: These define the layout for specific types of pages, like your homepage, a single blog post, your 404 error page, or your search results page. A Block Theme comes with default templates, but you can modify them or create your own from scratch without writing a single line of code.
  • Template Parts: These are reusable global elements, like your site’s header or footer. When you edit a template part, the change is instantly reflected across every template that uses it. This ensures consistency and saves a massive amount of time.

Global Styles

Global Styles is one of the most powerful features of FSE. It’s a design panel within the Site Editor that lets you control your site’s entire aesthetic from one place. Think of it as your site’s design DNA.

With Global Styles, you can set site-wide defaults for:

  • Typography: Choose and manage fonts, sizes, and weights for headings, paragraphs, links, and buttons across your entire site.
  • Colors: Create and apply a consistent color palette for your background, text, links, and various elements.
  • Layout: Define default padding, margins, and block spacing for a consistent look and feel.

You can even adjust styles on a per-block basis. For instance, you could decide that all “Button” blocks should have rounded corners and a specific background color by default. This system makes it incredibly easy to maintain a professional and consistent design.

Block Patterns

Block Patterns are pre-designed collections of blocks that you can insert into any page or template with a single click. They are professionally crafted layouts for common sections like “Call to Action,” “Testimonials,” “Pricing Table,” or “Team Members.”

Instead of building complex layouts from scratch, you can drop in a pattern and simply replace the placeholder content with your own. This dramatically speeds up the building process and provides a great starting point for beautiful designs. Theme developers, like us at AcmeThemes, can ship themes with a unique library of custom patterns that match the theme’s style.

Why FSE is the Future?

Full Site Editing isn’t just a new feature; it’s a fundamental improvement to the WordPress platform. Here’s why it’s here to stay.

  1. Ultimate User Empowerment: FSE puts design control directly into your hands. You are no longer limited by the options your theme developer decided to include. If you can imagine a layout, you can likely build it by moving blocks around.
  2. A Unified and Intuitive Experience: Gone are the days of jumping between the editor, the customizer, and widget menus. With FSE, everything happens in one place. This cohesive workflow is more intuitive for beginners and more efficient for experienced users.
  3. Faster Performance: Block Themes are inherently simpler and more lightweight. Because they don’t need the complex PHP logic or the Customizer framework of classic themes, they often load faster, which is a crucial factor for SEO and user experience. The WordPress core team has made performance a key priority with FSE development.
  4. Future-Proof Development: As WordPress continues to evolve, the block editor will remain at its core. By embracing FSE, you’re aligning your website with the future direction of the platform, ensuring better compatibility and access to new features down the line.

Getting Started with FSE

Ready to dive in? It’s easier than you think.

  1. Ensure WordPress is updated: FSE is a core feature, so you’ll need a modern version of WordPress (6.0 or newer is recommended).
  2. Install a Block Theme: Go to Appearance > Themes > Add New and use the “Block Themes” filter to find a theme built for FSE. The default WordPress theme (like Twenty Twenty-Four) is a great place to start.
  3. Explore the Site Editor: Navigate to Appearance > Editor. Don’t be afraid to click around! Open the “Templates” list to see all the layouts you can edit. Click on your header or footer to see how “Template Parts” work.
  4. Experiment with Global Styles: Open the Styles panel (the half-black, half-white circle icon) and play with the color palettes and typography settings. Watch your entire site transform in real-time.
  5. Leverage Patterns: When editing a page or template, click the + icon to add a block and explore the “Patterns” tab. You’ll find a treasure trove of ready-made designs.

Conclusion

Full Site Editing is the future of WordPress themes, offering unparalleled flexibility and ease of use. While it’s still maturing, its potential to democratize website design is undeniable.

As WordPress continues to embrace block-based editing, theme developers, designers, and users must adapt to stay ahead. Whether you’re a beginner or an advanced user, now is the time to explore FSE and harness its power for your next project.
