Unordered List

Create a list by starting a line with -
Make sub-lists by indenting 2 spaces:
- Marker character change forces new list start:
  - Ac tristique libero volutpat at
  - Facilisis in pretium nisl aliquet
  - Nulla volutpat aliquam velit
    link break
    New paragraph
It’s easy!

- Create a list by starting a line with `-`
- Sub-lists are made by indenting 2 spaces:

  - Marker character change forces new list start:

    - Ac tristique libero volutpat at
    - Facilisis in pretium nisl aliquet
    - Nulla volutpat aliquam velit

Code Block Highlight

We support highlighting in almost all languages.

Demo

<!doctype html>
<html lang="en">
  <head>
    <script>
      // Just a lil’ script to show off that inline JS gets highlighted
      window.console && console.log('foo');
    </script>
    <meta charset="utf-8" />
    <link rel="icon" href="assets/favicon.png" />
    <title>Prism</title>
    <link rel="stylesheet" href="assets/style.css" />
    <link rel="stylesheet" href="themes/prism.css" data-noprefix />
    <script src="assets/vendor/prefixfree.min.js"></script>

    <script>
      var _gaq = [['_setAccount', 'UA-33746269-1'], ['_trackPageview']];

Mathematical formula

You can use $ ... $ to create inline formulas, or use $$ ... $$ to create block-level formulas.

Demo

Euler’s identity $e^{i π} + 1 = 0$ is a beautiful formula in $R^{2}$ .

Euler’s identity $e^{i\pi}+1=0$ is a beautiful formula in $\mathbb{R}^2$.

\frac{\partial^{r}}{\partial ω^{r}} (\frac{y^{ω}}{ω}) = (\frac{y^{ω}}{ω}) {(\log y)^{r} + \sum_{i = 1}^{r} \frac{(- 1)^{i} r \dots (r - i + 1) (\log y)^{r - i}}{ω^{i}}}

$$
\frac {\partial^r} {\partial \omega^r} \left(\frac {y^{\omega}} {\omega}\right)
= \left(\frac {y^{\omega}} {\omega}\right) \left\{(\log y)^r + \sum_{i=1}^r \frac {(-1)^i r \cdots (r-i+1) (\log y)^{r-i}} {\omega^i} \right\}
$$
