·

Key Takeaways:

  • You can create a transparent header using only the Gutenberg editor—no plugins or custom CSS needed.
  • Transparent headers are applied individually per page, offering flexibility in design.
  • Proper alignment and padding adjustments are essential for a seamless transparent header effect.

Have you ever visited a website and admired its sleek, modern design featuring a transparent header? It looks professional, clean, and visually appealing. If you’re running a WordPress site built on the new Block Theme (Full Site Editing or FSE), you’re in luck! You can easily create this transparent header effect without any third-party plugins or custom CSS.

In this post, I’ll walk you through the exact steps to achieve a transparent header using only the core Gutenberg editor features. Whether you’re building your homepage or landing pages, this method works seamlessly across any block theme.

Understanding Transparent Headers in WordPress Block Themes

Before we start clicking around, let’s clarify what exactly we’re trying to achieve. A transparent header is essentially a header section that blends smoothly with the content below it—usually an image or video background. Instead of appearing as a separate block with its own background color, it merges visually with the hero section of your page.

One important thing to note is that transparent headers are applied individually per page. This means that if you set a transparent header for your homepage, your blog page or other pages will still have their original headers unless you manually apply this effect to those pages too.

Step-by-Step Guide: Creating Your Transparent Header

Let’s get practical! Follow these straightforward steps to add a transparent header to your WordPress block theme:

Step 1: Open Your WordPress Dashboard & Editor

First things first, log in to your WordPress dashboard. Navigate to Appearance → Editor. Here you’ll find all the tools you need for full-site editing.

Step 2: Select the Page You Want to Edit

Once inside the editor, select the specific page you’d like your transparent header on—typically your homepage or landing page. Remember, this setting applies individually per page.

Step 3: Prepare Your Hero Section

Your hero section usually contains an impactful image or video background. Make sure it’s large enough so part of it can extend behind your transparent header.

Step 4: Detach Your Header from Reusable Blocks

Many themes use reusable blocks for headers—great for consistency across multiple pages. But since we want our header unique and transparent on this particular page, we’ll detach it:

  • Open the List View by clicking its icon (three horizontal lines) at the top-left corner.
  • Find your header block (usually highlighted purple if it’s reusable).
  • Click on its options menu (three dots) and select Detach.

This converts it into a regular Gutenberg block that’s independent from other pages.

Step 5: Position Your Header Within the Hero Section

To blend seamlessly with your hero image or video, drag your detached header directly into your hero section:

  • In List View, click and drag your header block into the top position within the hero (cover) block.
  • Adjust alignment settings by selecting the cover block and choosing either Center or Top Center alignment from the toolbar options.

Step 6: Remove Padding & Adjust Positioning

You might notice there’s still some padding preventing perfect alignment at the very top of your page. To fix this:

  • Select your cover (hero) block.
  • Open Settings → Styles → Padding.
  • Set top padding to zero.

This ensures your header sits flush against the top edge of your webpage without gaps.

Step 7: Make Your Header Transparent

Now comes the fun part—making it actually transparent!

  • Select your header block again.
  • Go into Settings → Styles → Background.
  • Choose any color (the color itself doesn’t matter).
  • Adjust transparency by sliding opacity fully left until completely see-through.

Voilà! You’ve successfully created a sleek transparent header using nothing but core Gutenberg features.

Preview & Save Your Work

Always preview changes before going live:

  • Click Save, then select View Site.
  • Check how everything looks across different devices and screen sizes.

If you’re satisfied with how things turned out—great job! You’ve mastered one more powerful feature of Gutenberg’s full-site editing capabilities.

Additional Tips & Considerations

While creating transparent headers is straightforward once you know how, here are extra tips for best results:

  • Use high-quality images/videos that contrast well against text elements placed over them.
  • Keep navigation menus simple yet readable; transparency shouldn’t compromise usability.
  • Regularly test responsiveness across devices; ensure mobile users also enjoy seamless experiences.
