FAQPage Schema
How do I render math formulas in markdown and HTML content?

To render math formulas in markdown and HTML, you can use KaTeX to convert TeX syntax into insertion-ready HTML snippets. This provides consistent, accessible math formatting across static documents and web applications.

What is the best way to display inline and block equations in MDX?

Displaying inline and block equations in MDX is best handled by rendering TeX math into pre-rendered HTML fragments. This approach supports both inline and display modes while preserving your mathematical notation delimiters.

Can I use pre-rendered HTML fragments for static math equations?

Pre-rendered HTML fragments work well for static math equations by generating insertion-ready KaTeX output during your build process. This ensures consistent formatting without requiring client-side JavaScript execution.

Does KaTeX auto-render support editable content with TeX delimiters?

KaTeX auto-render supports editable content by automatically finding and rendering TeX delimiters on the client side. This allows dynamic content to display math formulas correctly while keeping the original notation editable.

How do I handle errors when rendering TeX math into web pages?

Handling errors when rendering TeX math involves using robust error-handling options provided by the KaTeX renderer. This prevents broken layouts by safely managing unsupported macros or syntax issues during equation rendering.

Do I need specific dependencies to support macros in math rendering?

Supporting macros in math rendering requires the KaTeX dependency to process and expand your custom TeX macro definitions. This enables consistent reuse of complex mathematical expressions across your HTML or MDX content.
