  40. Getting the Gist of Markdown's Formatting Syntax
  41. ------------------------------------------------
  42. This page offers a brief overview of what it's like to use Markdown.
  43. The [syntax page] [s] provides complete, detailed documentation for
  44. every feature, but Markdown should be very easy to pick up simply by
  45. looking at a few examples of it in action. The examples on this page
  46. are written in a before/after style, showing example syntax and the
  47. HTML output produced by Markdown.
  48. It's also helpful to simply try Markdown out; the [Dingus] [d] is a
  49. web application that allows you type your own Markdown-formatted text
  50. and translate it to XHTML.
  51. **Note:** This document is itself written using Markdown; you
  52. can [see the source for it by adding '.text' to the URL] [src].

  56. ## Paragraphs, Headers, Blockquotes ##
  57. A paragraph is simply one or more consecutive lines of text, separated
  58. by one or more blank lines. (A blank line is any line that looks like
  59. a blank line -- a line containing nothing but spaces or tabs is
  60. considered blank.) Normal paragraphs should not be indented with
  61. spaces or tabs.
  62. Markdown offers two styles of headers: *Setext* and *atx*.
  63. Setext-style headers for `&lt;h1&gt;` and `&lt;h2&gt;` are created by
  64. "underlining" with equal signs (`=`) and hyphens (`-`), respectively.
  65. To create an atx-style header, you put 1-6 hash marks (`#`) at the
  66. beginning of the line -- the number of hashes equals the resulting
  67. HTML header level.
  68. Blockquotes are indicated using email-style '`&gt;`' angle brackets.
  69. Markdown:
  70. A First Level Header
  71. ====================
  72. A Second Level Header
  73. ---------------------
  74. Now is the time for all good men to come to
  75. the aid of their country. This is just a
  76. regular paragraph.
  77. The quick brown fox jumped over the lazy
  78. dog's back.
  79. ### Header 3
  80. &gt; This is a blockquote.
  81. &gt;
  82. &gt; This is the second paragraph in the blockquote.
  83. &gt;
  84. &gt; ## This is an H2 in a blockquote
  85. Output:
  86. &lt;h1&gt;A First Level Header&lt;/h1&gt;
  87. &lt;h2&gt;A Second Level Header&lt;/h2&gt;
  88. &lt;p&gt;Now is the time for all good men to come to
  89. the aid of their country. This is just a
  90. regular paragraph.&lt;/p&gt;
  91. &lt;p&gt;The quick brown fox jumped over the lazy
  92. dog's back.&lt;/p&gt;
  93. &lt;h3&gt;Header 3&lt;/h3&gt;
  94. &lt;blockquote&gt;
  95. &lt;p&gt;This is a blockquote.&lt;/p&gt;
  96. &lt;p&gt;This is the second paragraph in the blockquote.&lt;/p&gt;
  97. &lt;h2&gt;This is an H2 in a blockquote&lt;/h2&gt;
  98. &lt;/blockquote&gt;
  99. ### Phrase Emphasis ###
  100. Markdown uses asterisks and underscores to indicate spans of emphasis.
  101. Markdown:
  102. Some of these words *are emphasized*.
  103. Some of these words _are emphasized also_.
  104. Use two asterisks for **strong emphasis**.
  105. Or, if you prefer, __use two underscores instead__.
  106. Output:
  107. &lt;p&gt;Some of these words &lt;em&gt;are emphasized&lt;/em&gt;.
  108. Some of these words &lt;em&gt;are emphasized also&lt;/em&gt;.&lt;/p&gt;
  109. &lt;p&gt;Use two asterisks for &lt;strong&gt;strong emphasis&lt;/strong&gt;.
  110. Or, if you prefer, &lt;strong&gt;use two underscores instead&lt;/strong&gt;.&lt;/p&gt;
  111. ## Lists ##
  112. Unordered (bulleted) lists use asterisks, pluses, and hyphens (`*`,
  113. `+`, and `-`) as list markers. These three markers are
  114. interchangable; this:
  115. * Candy.
  116. * Gum.
  117. * Booze.
  118. this:
  119. + Candy.
  120. + Gum.
  121. + Booze.
  122. and this:
  123. - Candy.
  124. - Gum.
  125. - Booze.
  126. all produce the same output:
  127. &lt;ul&gt;
  128. &lt;li&gt;Candy.&lt;/li&gt;
  129. &lt;li&gt;Gum.&lt;/li&gt;
  130. &lt;li&gt;Booze.&lt;/li&gt;
  131. &lt;/ul&gt;
  132. Ordered (numbered) lists use regular numbers, followed by periods, as
  133. list markers:
  134. 1. Red
  135. 2. Green
  136. 3. Blue
  137. Output:
  138. &lt;ol&gt;
  139. &lt;li&gt;Red&lt;/li&gt;
  140. &lt;li&gt;Green&lt;/li&gt;
  141. &lt;li&gt;Blue&lt;/li&gt;
  142. &lt;/ol&gt;
  143. If you put blank lines between items, you'll get `&lt;p&gt;` tags for the
  144. list item text. You can create multi-paragraph list items by indenting
  145. the paragraphs by 4 spaces or 1 tab:
  146. * A list item.
  147. With multiple paragraphs.
  148. * Another item in the list.
  149. Output:
  150. &lt;ul&gt;
  151. &lt;li&gt;&lt;p&gt;A list item.&lt;/p&gt;
  152. &lt;p&gt;With multiple paragraphs.&lt;/p&gt;&lt;/li&gt;
  153. &lt;li&gt;&lt;p&gt;Another item in the list.&lt;/p&gt;&lt;/li&gt;
  154. &lt;/ul&gt;
  155. ### Links ###
  156. Markdown supports two styles for creating links: *inline* and
  157. *reference*. With both styles, you use square brackets to delimit the
  158. text you want to turn into a link.
  159. Inline-style links use parentheses immediately after the link text.
  160. For example:
  161. This is an [example link](http://example.com/).
  162. Output:
  163. &lt;p&gt;This is an &lt;a href="http://example.com/"&gt;
  164. example link&lt;/a&gt;.&lt;/p&gt;
  165. Optionally, you may include a title attribute in the parentheses:
  166. This is an [example link](http://example.com/ "With a Title").
  167. Output:
  168. &lt;p&gt;This is an &lt;a href="http://example.com/" title="With a Title"&gt;
  169. example link&lt;/a&gt;.&lt;/p&gt;
  170. Reference-style links allow you to refer to your links by names, which
  171. you define elsewhere in your document:
  172. I get 10 times more traffic from [Google][1] than from
  173. [Yahoo][2] or [MSN][3].
  174. [1]: http://google.com/ "Google"
  175. [2]: http://search.yahoo.com/ "Yahoo Search"
  176. [3]: http://search.msn.com/ "MSN Search"
  177. Output:
  178. &lt;p&gt;I get 10 times more traffic from &lt;a href="http://google.com/"
  179. title="Google"&gt;Google&lt;/a&gt; than from &lt;a href="http://search.yahoo.com/"
  180. title="Yahoo Search"&gt;Yahoo&lt;/a&gt; or &lt;a href="http://search.msn.com/"
  181. title="MSN Search"&gt;MSN&lt;/a&gt;.&lt;/p&gt;
  182. The title attribute is optional. Link names may contain letters,
  183. numbers and spaces, but are *not* case sensitive:
  184. I start my morning with a cup of coffee and
  185. [The New York Times][NY Times].
  186. [ny times]: http://www.nytimes.com/
  187. Output:
  188. &lt;p&gt;I start my morning with a cup of coffee and
  189. &lt;a href="http://www.nytimes.com/"&gt;The New York Times&lt;/a&gt;.&lt;/p&gt;
  190. ### Images ###
  191. Image syntax is very much like link syntax.
  192. Inline (titles are optional):
  193. ![alt text](/path/to/img.jpg "Title")
  194. Reference-style:
  195. ![alt text][id]
  196. [id]: /path/to/img.jpg "Title"
  197. Both of the above examples produce the same output:
  198. &lt;img src="/path/to/img.jpg" alt="alt text" title="Title" /&gt;
  199. ### Code ###
  200. In a regular paragraph, you can create code span by wrapping text in
  201. backtick quotes. Any ampersands (`&amp;`) and angle brackets (`&lt;` or
  202. `&gt;`) will automatically be translated into HTML entities. This makes
  203. it easy to use Markdown to write about HTML example code:
  204. I strongly recommend against using any `&lt;blink&gt;` tags.
  205. I wish SmartyPants used named entities like `&amp;mdash;`
  206. instead of decimal-encoded entites like `&amp;#8212;`.
  207. Output:
  208. &lt;p&gt;I strongly recommend against using any
  209. &lt;code&gt;&amp;lt;blink&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;
  210. &lt;p&gt;I wish SmartyPants used named entities like
  211. &lt;code&gt;&amp;amp;mdash;&lt;/code&gt; instead of decimal-encoded
  212. entites like &lt;code&gt;&amp;amp;#8212;&lt;/code&gt;.&lt;/p&gt;
  213. To specify an entire block of pre-formatted code, indent every line of
  214. the block by 4 spaces or 1 tab. Just like with code spans, `&amp;`, `&lt;`,
  215. and `&gt;` characters will be escaped automatically.
  216. Markdown:
  217. If you want your page to validate under XHTML 1.0 Strict,
  218. you've got to put paragraph tags in your blockquotes:
  219. &lt;blockquote&gt;
  220. &lt;p&gt;For example.&lt;/p&gt;
  221. &lt;/blockquote&gt;
  222. Output:
  223. &lt;p&gt;If you want your page to validate under XHTML 1.0 Strict,
  224. you've got to put paragraph tags in your blockquotes:&lt;/p&gt;
  225. &lt;pre&gt;&lt;code&gt;&amp;lt;blockquote&amp;gt;
  226. &amp;lt;p&amp;gt;For example.&amp;lt;/p&amp;gt;
  227. &amp;lt;/blockquote&amp;gt;
  228. &lt;/code&gt;&lt;/pre&gt;
  229. ## Fenced code blocks (and syntax highlighting)
  230. ```javascript
  231. for (var i = 0; i < items.length; i++) {
  232. console.log(items[i], i); // log them
  233. }
  234. ```
  235. </textarea></form>

  237. var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
