LaTeX.css is a minimal, almost class-less CSS library which makes any website look like a LaTeX document. It is based on @davidrzs'latexCSS.
Using the <link> tag
Add the following code in the head of your project.
<link rel="stylesheet" href="https://latex.now.sh/style.min.css" />
or use a CDN like Unpkg:
<link rel="stylesheet" href="https://unpkg.com/latex.css/style.min.css" />
npm install latex.css
yarn add latex.css
Add any optional classnames to elements with special styles (author subtitle, abstract, lemmas, theorems, etc.). A list of supported class-based elements can be found here.
