How to Create a Custom Author Box in WordPress (No Plugins)

Establishing a personal connection between your readers and your articles is the best way to build authority. While WordPress provides a basic “Author Bio” field, it often dosen’t look very good.

In this tutorial, we are going to build a Smart Author Box Creator. This isn’t just a static design; it’s a dynamic tool that lets you customize the layout, social links, and vibe to match how your brand looks. By the end of this guide, you’ll have a professional, lightweight code snippet that works without the weight of a heavy plugin.

    Why Every Site Needs a Custom Author Box

    In the age of AI-generated content, E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is the most important thing for Google. A well-designed author box proves there is a real human with real credentials behind the keyboard.

    A custom author box allows you to:

    • Humanize your brand: Show the face behind the facts.
    • Drive Social Following: Directly link to LinkedIn, Twitter, or Portfolios.
    • Improve Retention: Readers who trust an author are 40% more likely to click on another article by that same person.

    The Build Your Custom Author Box

    Use the generator below to choose your style and copy the code. We have included five ultra-cool presets: Classic, Modern Blue, Industrial, Paper Fold, and Night Glow.

</style>
<!-- END AUTHOR BOX -->

    Part 1: Customizing Your Information

    The generated code uses placeholders. To make this box truly yours, you need to swap out the text and images. Here is exactly what to change:

    1. The Author Image

    Find YOUR_IMAGE_URL in the HTML section.

    • Pro Tip: Upload your photo to your WordPress Media Library, click on the image, and copy the “File URL.” Paste that URL into the code.
    • Size Matters: The code automatically constrains the image to 90px by 90px, but it’s best to use a square-cropped image for the cleanest look.

    2. The Bio Text

    Don’t just list your job title. Use the “auth-bio” section to explain why the reader should listen to you.

    • Bad Bio: “John is a writer.”
    • Good Bio: “John has spent 12 years in cybersecurity, helping over 500 companies protect their data.

    Part 2: Advanced Style Customizations

    If you want to go beyond our presets, you can tweak the CSS variables directly in the code block.

    Rounding the Corners

    In the #author-box-wrap section, look for border-radius.

    • Set it to 0px for a sharp, professional look.
    • Set it to 50px for a “pill” shaped design.

    Responsiveness

    The code includes a “media query” at the bottom. This ensures that on small smartphone screens, the image centers itself above the text instead of being squished to the left. This is vital for mobile SEO.

    Part 3: How to Install in WordPress

    Since this is a lightweight HTML/CSS solution, you have three ways to implement it:

    Option A: The Block Editor (Gutenberg)

    If you only want the author box on specific long-form articles:

    1. Open your post editor.
    2. Add a Custom HTML block.
    3. Paste the code and hit update.

    Option B: Theme File Editor (Automated)

    If you want the box to appear on every post automatically:

    1. Go to Appearance > Theme File Editor.
    2. Find single.php.
    3. Paste the code right after the_content();.
    • Warning: Always use a Child Theme when editing core files!

    Option C: Reusable Blocks

    Create the author box once in a “Reusable Block” (now called “Patterns”). This allows you to drop it into any post with two clicks without ever touching the code again.
