- <ul class="features">
- <li><b>Fast:</b> KaTeX renders its math synchronously and doesn’t need to reflow the page.</li>
- <li><b>Print quality:</b> KaTeX’s layout is based on Donald Knuth’s TeX, the gold standard for math typesetting.</li>
- <li><b>Self contained:</b> KaTeX has no dependencies and can easily be bundled with your website resources.</li>
- <li><b>Server side rendering:</b> KaTeX produces the same output regardless of browser or environment, so you can pre-render expressions using Node.js and send them as plain HTML.</li>
