MathML
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2023.
Mathematical Markup Language (MathML) is anXML-based language for describing mathematical notation.
MathML was originally designed as a general-purpose specification for browsers, office suites,computer algebra systems,EPUB readers,LaTeX-based generators. However, this approach was not very adapted to the Web: thesubset focusing on semantics has never been implemented in browsers while thesubset focusing on math layout led to incomplete and inconsistent browser implementations.
MathML Core is a subset with increased implementation details based on rules fromLaTeX and theOpen Font Format. It is tailored for browsers and designed specifically to work well with other web standards includingHTML,CSS,DOM,JavaScript.
Below you will find links to documentation, examples, and tools to work with MathML. MDN usesMathML Core as a reference specification but, due to an erratic standardization history, legacy MathML features may still show up in existing implementations and web content.
Note:It is highly recommended that developers and authors switch to MathML Core, perhaps relying on other web technologies to cover missing use cases. The Math WG is maintaining a set ofMathML polyfills to facilitate that transition.
Tutorials
TheMathML tutorials are designed to walk you through topics assuming that you have no prior experience, starting from the basics and progressing to more advanced techniques.
- MathML for beginners
This tutorial will guide you through creating math formulas using structured markup. It starts with an introduction to adding MathML to an HTML document, followed by a deep dive into key components: fractions and roots, scripted elements, and text containers. The tutorial then covers tabular layouts for matrices and advanced math formatting. Finally, a challenge tests your understanding by having you recreate three famous mathematical formulas using the learned concepts.
Guides
TheMathML guides are resources that help you author MathML on your web pages, including guidance on writing, editors, fonts and more.
- Authoring MathML
Suggestions and tips for writing MathML, including suggested MathML editors and how to integrate their output into Web content.
- Fonts for MathML
How users can install such math fonts to properly display MathML in browsers.
Reference
TheMathML reference is a comprehensive list of MathML elements and attributes that are documented on MDN.
- MathML element reference
Details about each MathML element and compatibility information for desktop and mobile browsers.
- MathML global attribute reference
Information about global MathML attributes applicable to all elements.
- MathML attribute reference
Information about MathML attributes that modify the appearance or behavior of elements.
