Fix Edge Browser Translation Issues with <code> Tags

Introduction

On Windows, the default browser is Microsoft Edge, built on the Chromium engine, providing performance and rendering similar to Chrome. However, differences in translation functionality may cause issues with <code> tags in Edge. These problems can be mitigated by wrapping <code> tags with additional <span> tags.

Differences Between Edge and Chrome in Translation

When reading complex articles, translation tools can help make content more understandable. However, translating pages with <code> tags often yields differing results:

In the example, Chrome accurately preserves the position of <code> tags, maintaining structure and clarity. Conversely, Edge misplaces <code> tags, inserting them incorrectly at the end of sentences, which disrupts readability.

This issue was raised as early as November 2020 in Microsoft Community Hub but remains unresolved as of early 2025.

Fixing Hugo Blog Post Rendering Issues

For blogs built with Hugo, you can update templates to optimize rendering and translation experiences. Here’s a patch to fix the content.html template:

 </section>

This modification ensures <code> elements are wrapped in <span> tags during rendering, preventing translation issues in Edge.

Installing a User Script to Fix All Webpages

To address this issue across all websites, use a user script. Below is the script content:

    /**
     * Wrap a single <code> element with a <span>
     * @param {HTMLElement} codeNode - The <code> element to wrap
     */
    const wrapSingleCode = (codeNode) => {
        if (!codeNode.parentNode || codeNode.parentNode.tagName === "SPAN") return; // Skip if already wrapped
        const spanNode = document.createElement("span")
        codeNode.parentNode.replaceChild(spanNode, codeNode)
        spanNode.appendChild(codeNode)
    }

    // Wrap all <code> elements on initial load
   document.querySelectorAll("code").forEach(wrapSingleCode)
})()

This script wraps all <code> tags with <span> tags upon page load and monitors for dynamic changes to handle newly added <code> elements.

Conclusion

While a small number of web pages may experience translation layout issues in Chrome, Edge consistently struggles with <code> tags during translation. This issue can be resolved effectively by updating Hugo templates or using user scripts. These solutions ensure a significantly improved reading experience after translation, preserving the clarity and structure of the content.
