  • Filtered HTML:
    • Web page addresses and e-mail addresses turn into links automatically.

    • Allowed HTML tags: <a> <em> <strong> <cite> <code> <ul> <ol> <li> <dl> <dt> <dd>

      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 W3C's HTML Specifications or use your favorite search engine to find other sites that explain HTML.

      Definition lists are similar to other HTML lists. <dl> begins the definition list, <dt> begins the definition term and <dd> begins the definition description.<dl> <dt>First term</dt> <dd>First definition</dd> <dt>Second term</dt> <dd>Second definition</dd> </dl>
      First term

      Second term

      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:

    • 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 blank lines.

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

      • Generic syntax highlighting tags: "<code>", "<blockcode>".
      • Language specific syntax highlighting tags: "<bash>" for Bash source code, "<c>" for C source code, "<cpp>" for C++ source code, "<java>" for Java source code, "<python>" for Python 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. The possible values are: "bash" (for Bash), "c" (for C), "cpp" (for C++), "html4strict" (for HTML), "java" (for Java), "mysql" (for MySQL), "python" (for Python), "xml" (for XML).
      • 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 nth 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.
      • Beside the tag style "<foo>" it is also possible to use "[foo]".

      Defaults:

      • Default highlighting mode for generic syntax highlighting tags: when no language attribute is specified, no syntax highlighting will be done.
      • Default line numbering: no line numbers.

      Examples:

      You typeYou get
      <code>foo = "bar";</code>Inline code with the default syntax highlighting mode.
      <code>
      foo = "bar";
      baz = "foz";
      </code>      		Code block with the default syntax highlighting mode.
      <code lang="python" linenumbers="normal">
      foo = "bar";
      baz = "foz";
      </code>      		Code block with syntax highlighting for Python source code
      and normal line numbers.
      <code language="python" start="23" fancy="7">
      foo = "bar";
      baz = "foz";
      </code>      		Code block with syntax highlighting for Python source code,
      line numbers starting from 23
      and highlighted line numbers every 7th line.
      <bash>
      foo = "bar";
      baz = "foz";
      </bash>      		Code block with syntax highlighting for Bash source code.
      <bash start="23" fancy="7">
      foo = "bar";
      baz = "foz";
      <bash>      		Code block with syntax highlighting for Bash source code,
      line numbers starting from 23
      and highlighted line numbers every 7th line.
