No, LaTeX is not part of the HTML standard. HTML (HyperText Markup Language) and LaTeX are separate markup languages designed for different purposes:

• HTML is the standard markup language for creating web pages and web applications. It defines the structure and content of a webpage, such as text, images, links, and other elements.
• LaTeX is a typesetting system primarily used for scientific and mathematical documents, known for its precise control over formatting, especially for complex equations and academic papers.

While HTML is a web standard maintained by organizations like the W3C, LaTeX is a document preparation system and has its own syntax and ecosystem. However, you can render LaTeX expressions in HTML using libraries like MathJax or KaTeX, which allow LaTeX math notation to be displayed in web browsers. These libraries convert LaTeX into formats that browsers can render, such as SVG or MathML.
