How to Choose the Right Theme for Your Site
With so many great WordPress themes available, it can be hard to pick the right one, especially when using a powerful block plugin like B Blocks. To get the most out of its layout and design features, your theme should match your workflow, design goals, and performance needs.
Here’s what to consider when choosing a theme that works best with B Blocks:
FSE vs Classic: Which Workflow Suits You?
- FSE themes (like Twenty Twenty-Five, Neve FSE, and Ollie) give you full visual control over your site’s structure. You can edit headers, footers, templates, and more directly in the block editor.
- Classic themes (like Astra, GeneratePress, and Kadence) use the WordPress Customizer for styling but still support block-based layouts and work well with B Blocks.
Choose FSE if: You want full design flexibility and are comfortable using the Site Editor.
Choose Classic if: You prefer a familiar Customizer interface or prioritize fast performance and stability.
Key Features to Look For
To make the most of B Blocks, your theme should support:
- Flexible layout controls: Full-width vs. boxed options, adjustable container widths, and margin/padding settings.
- Global styling options: Typography, spacing, and color controls via the Customizer or Site Editor.
- Performance optimization: Clean code, minimal bloat, and good Core Web Vitals scores.
- Accessibility and mobile responsiveness: WCAG-compliant and fully responsive across devices.
- Plugin compatibility: Themes should work well with block plugins like B Blocks without limiting design freedom.
Match Your Theme to Your Project Goals
Different themes serve different use cases. Here are a few suggestions based on common site types:
| Use Case | Recommended Themes |
| Blogs & Portfolios | Twenty Twenty-Five, Ollie, GeneratePress, Blocksy |

- Ongoing Support & Updates: Choose themes backed by reliable developers with frequent updates and strong documentation.
- Multilingual & RTL Support: If you’re building a multilingual site, check for compatibility with WPML, Polylang, and RTL text support.

No. B Blocks is built for performance. As long as you choose a lightweight, well-coded theme—like Neve, GeneratePress, or Blocksy—your site should stay fast. Avoid themes packed with unnecessary scripts or design features that might interfere with block styling.

9. What if my theme conflicts with B Blocks’ styling?
Most modern themes work well with B Blocks out of the box. If you notice layout or style issues, try adjusting global styles, disabling the theme’s block styling, or using B Blocks’ built-in layout controls to override those conflicts.
