FSE Series 1: What is WordPress Full Site Editing (FSE)? And Why You Should Care
Target Audience: WordPress users familiar with the Block Editor (Gutenberg) but new to FSE.
Introduction
WordPress has always been about democratizing web design, and Full Site Editing (FSE) is its boldest leap yet. Imagine controlling your entire website—headers, footers, layouts, and styles—without touching a line of code or relying on third-party plugins. That’s FSE in a nutshell.
In this first post, we’ll unpack what FSE is, why it’s a game-changer for designers and developers, and how the Twenty Twenty-Five theme gives you the perfect playground to master it. Let’s get started!
What is Full Site Editing?
FSE is WordPress’s block-based approach to theming and site customization. Unlike classic themes, where PHP templates dictate your site’s structure, FSE hands you the reins with:
- The Site Editor: A unified workspace to design every part of your site (headers, footers, archives, etc.) using blocks.
- Global Styles: A centralized system to set typography, colors, and spacing across your entire site.
- Block Patterns & Templates: Pre-designed layouts and reusable sections to speed up your workflow.
Think of it as the Block Editor (Gutenberg) graduating from editing pages to controlling your entire site.
Why it matters:
- 🚀 No more theme hopping: Customize layouts directly instead of hunting for “the perfect theme.”
- 🎨 Design consistency: Global Styles ensure your brand looks cohesive everywhere.
- ⏱️ Faster iterations: Update headers, footers, or templates in minutes, not hours.
WordPress.org calls FSE “the future of theming”—and for good reason.
FSE vs. Classic Themes: What’s the Difference?
Let’s break down how FSE flips traditional WordPress theming on its head:
| Classic Themes | FSE Themes (Like Twenty Twenty-Five) |
|---|---|
| PHP templates control design | Blocks and HTML templates control design |
| Customize via Customizer | Customize via Site Editor |
| Limited header/footer edits | Edit headers/footers like any other page |
| Requires CSS/plugins for tweaks | Style everything visually with Global Styles |
Example: Changing a header in a classic theme might involve editing header.php or paying for a plugin. With FSE, you just open the Site Editor, drag-and-drop blocks, and hit save.
Why Learn FSE Now?
- WordPress is All-In on Blocks
The Block Editor (Gutenberg) launched in 2018, and FSE is its natural evolution. Over 43% of all websites use WordPress—mastering FSE puts you ahead of the curve. - Simpler Workflows, Fewer Plugins
FSE reduces reliance on page builders (like Elementor) and theme frameworks (like Divi). Less plugins mean faster sites and fewer updates to manage. - Future-Proof Skills
As more themes adopt FSE (like Twenty Twenty-Three, Twenty Twenty-Four, and Twenty Twenty-Five), developers who understand block-based theming will be in high demand.
Why Twenty Twenty-Five is the Perfect FSE Starter Theme
Twenty Twenty-Five is WordPress’s default FSE-ready theme for 2025 (currently in development, but you can download it here). Here’s why we’re using it:
- Minimalist Design: A clean canvas to focus on learning FSE tools.
- Block Patterns Galore: Pre-built sections for headers, grids, and calls-to-action.
- Full Compatibility: Built to showcase the latest FSE features.

Q: Do I need coding skills for FSE?
A: Not at all! FSE is designed for visual editing. Basic HTML/CSS helps for advanced tweaks, but it’s optional.
Q: Can I use FSE with any theme?
A: Only themes built for FSE (like Twenty Twenty-Five) support the Site Editor. Classic themes won’t work.
