USING TEXTILE
Block modifier syntax:
Header: hn.
Paragraphs beginning with 'hn. ' (where n is 1-6) are wrapped in header tags.
Example: <h1>Text</h1>
Header with CSS class: hn(class).
Paragraphs beginning with 'hn(class). ' receive a CSS class attribute.
Example: <h1 class="class">Text</h1>
Paragraph: p. (applied by default)
Paragraphs beginning with 'p. ' are wrapped in paragraph tags.
Example: <p>Text</p>
Paragraph with CSS class: p(class).
Paragraphs beginning with 'p(class). ' receive a CSS class attribute.
Example: <p class="class">Text</p>
Blockquote: bq.
Paragraphs beginning with 'bq. ' are wrapped in block quote tags.
Example: <blockquote>Text</blockquote>
Blockquote with citation: bq(citeurl).
Paragraphs beginning with 'bq(citeurl). ' receive a citation attribute.
Example: <blockquote cite="citeurl">Text</blockquote>
Numeric list: #
Consecutive paragraphs beginning with # are wrapped in ordered list tags.
Example: <ol><li>ordered list</li></ol>
Bulleted list: *
Consecutive paragraphs beginning with * are wrapped in unordered list tags.
Example: <ul><li>unordered list</li></ul>
Phrase modifier syntax:
_emphasis_ <em>emphasis</em>
__italic__ <i>italic</i>
*strong* <strong>strong</strong>
**bold** <b>bold</b>
??citation?? <cite>citation</cite>
-deleted text- <del>deleted</del>
+inserted text+ <ins>inserted</ins>
