Creating User-friendly Error Pages Without Causing Layout Shifts

by

When a user encounters an error page, such as a 404 or server error, it can be frustrating. A well-designed error page not only informs the user but also maintains a seamless experience without causing layout shifts. This article explores strategies to create user-friendly error pages that are visually stable and engaging.

Understanding Layout Shifts

Layout shifts occur when content moves unexpectedly as a page loads. This can happen if images or elements are loaded asynchronously or if the page’s structure is not properly reserved for dynamic content. For error pages, avoiding layout shifts ensures users remain engaged and trust your site’s professionalism.

Design Principles for Stable Error Pages

  • Reserve space for images and icons: Use CSS to allocate space for elements like logos or illustrations so they don’t cause shifts when loaded.
  • Use inline SVGs or optimized images: These load faster and are less likely to cause layout shifts.
  • Maintain consistent typography: Keep font sizes and styles consistent to avoid reflows.
  • Limit dynamic content: Avoid loading unnecessary scripts or content that could push elements around.

Implementing User-friendly Error Pages

Here are practical steps to create effective error pages:

  • Use a static layout: Design the page with a fixed layout that doesn’t rely heavily on external content.
  • Include helpful messaging: Clearly explain the error and provide navigation options.
  • Design with accessibility in mind: Ensure text is readable and navigation is straightforward.
  • Test for layout stability: Use browser tools to verify no unexpected shifts occur during page load.

Best Practices and Tools

Utilize tools like Google Lighthouse or WebPageTest to analyze your error pages for layout stability. Implement best practices such as setting explicit width and height attributes on images and videos. Consider using CSS techniques like aspect-ratio to preserve layout during loading.

Conclusion

Creating user-friendly error pages that do not cause layout shifts enhances user experience and maintains your website’s professionalism. By reserving space for dynamic content, optimizing assets, and following best practices, you can ensure your error pages are both informative and stable.
