  This site allows HTML content. While learning all of HTML may feel intimidating, learning how to use a very small number of the most basic HTML "tags" is very easy. This table provides examples for each tag that is enabled on this site.

  For more information see the HTML Living Standard or use your favorite search engine to find other sites that explain HTML.

  Tag Description	You Type	You Get
  By default line break tags are automatically added, so use this tag to add additional ones. Use of this tag is different because it is not used with an open/close pair like all the others. Use the extra " /" inside the tag to maintain XHTML 1.0 compatibility	Text with <br />line break	Text with line break

  Most unusual characters can be directly entered without any problems.

  If you do encounter problems, try using HTML character entities. A common example looks like &amp; for an ampersand & character. For a full list of entities see HTML's entities page. Some of the available characters include:

  Character Description	You Type	You Get
  Ampersand	&	&
  Greater than	>	>
  Less than	&lt;	<
  Quotation mark	&quot;	"

• Lines and paragraphs are automatically recognized. The <br /> line break, <p> paragraph and </p> close paragraph tags are inserted automatically. If paragraphs are not recognized simply add a couple of blank lines.

• Syntax highlighting of source code can be enabled with the following tags:

  Generic syntax highlighting tags: <code>, <blockcode>, <pre>.
  • Language specific syntax highlighting tags:<bash> for Bash source code, <cpp> for C++ source code, <js> for Javascript source code, <latex> for LaTeX source code, <perl> for Perl source code

  Options and tips:

  • The language for the generic syntax highlighting tags can be specified with one of the attribute(s): type, lang, language, class. The possible values are: "bash" (for Bash), "cpp" (for C++), "css" (for CSS), "html5" (for HTML5), "javascript" (for Javascript), "js" (for Javascript), "latex" (for LaTeX), "pcre" (for PCRE), "perl" (for Perl), "plsql" (for PL/SQL), "postgresql" (for PostgreSQL), "xml" (for XML), "yaml" (for YAML).
  • The supported tag styles are: <foo>, [foo].
  • Line numbering can be enabled/disabled with the attribute "linenumbers". Possible values are: "off" for no line numbers, "normal" for normal line numbers and "fancy" for fancy line numbers (every n^th line number highlighted). The start line number can be specified with the attribute "start", which implicitly enables normal line numbering. For fancy line numbering the interval for the highlighted line numbers can be specified with the attribute "fancy", which implicitly enables fancy line numbering.
  • If the source code between the tags contains a newline (e.g. immediatly after the opening tag), the highlighted source code will be displayed as a code block. Otherwise it will be displayed inline.
  • A title can be added to a code block with the attribute "title".

  Defaults:

  • Default highlighting mode for generic syntax highlighting tags: when no language attribute is specified the code block won't be processed by the GeSHi filter.
  • Default line numbering: no line numbers.
