I wonder if there is a framework or something else to display Math formula on a web page. Other than using images of those formulas...

I found this https://github.com/mathjax/mathjax very useful. It supports: <ul> <li>AsciiMath</li> <li>LaTeX</li> <li>Tex</li> <li>MathML</li> </ul>

<h3>Katex</h3> A couple of developers from the Khan Academy released a blazing quick library based off of Tex called Katex: <ul> <li>Fast</li> <li>High-quality </li> <li>Self-contained; and,</li> <li>Can be rendered on the server</li> </ul> Looks like a great modern option. <img src="https://i.stack.imgur.com/7E9Js.png" alt="Katex sample">
