    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.

    Anchors are used to make links to other pages.	<a href="http://desktopgisbook.com">Desktop GIS - the book</a>	Desktop GIS - the book

    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 First definition Second term Second definition

    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 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: .

    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: "abap" (for ABAP), "actionscript" (for ActionScript), "ada" (for Ada), "apache" (for Apache Log), "applescript" (for AppleScript), "asm" (for ASM), "asp" (for ASP), "autoit" (for AutoIt), "bash" (for Bash), "blitzbasic" (for BlitzBasic), "bnf" (for bnf), "c" (for C), "c_mac" (for C (Mac)), "caddcl" (for CAD DCL), "cadlisp" (for CAD Lisp), "cfdg" (for CFDG), "cfm" (for ColdFusion), "cpp" (for C++), "cpp-qt" (for C++ (QT)), "csharp" (for C#), "css" (for CSS), "d" (for D), "delphi" (for Delphi), "diff" (for Diff), "div" (for DIV), "dos" (for DOS), "dot" (for dot), "drupal5" (for Drupal 5), "drupal6" (for Drupal 6), "eiffel" (for Eiffel), "fortran" (for Fortran), "freebasic" (for FreeBasic), "genero" (for genero), "gml" (for GML), "groovy" (for Groovy), "haskell" (for Haskell), "html4strict" (for HTML), "idl" (for Uno Idl), "ini" (for INI), "inno" (for Inno), "io" (for Io), "java" (for Java), "java5" (for Java(TM) 2 Platform Standard Edition 5.0), "javascript" (for Javascript), "latex" (for LaTeX), "lisp" (for Lisp), "lua" (for Lua), "m68k" (for Motorola 68000 Assembler), "matlab" (for Matlab M), "mirc" (for mIRC Scripting), "mpasm" (for Microchip Assembler), "mysql" (for MySQL), "nsis" (for NSIS), "objc" (for Objective C), "ocaml" (for OCaml), "ocaml-brief" (for OCaml), "oobas" (for OpenOffice.org Basic), "oracle8" (for Oracle 8 SQL), "pascal" (for Pascal), "per" (for per), "perl" (for Perl), "php" (for PHP), "php-brief" (for PHP), "plsql" (for PL/SQL), "python" (for Python), "qbasic" (for QBasic/QuickBASIC), "rails" (for Rails), "reg" (for Microsoft Registry), "robots" (for robots.txt), "ruby" (for Ruby), "sas" (for SAS), "scheme" (for Scheme), "sdlbasic" (for sdlBasic), "smalltalk" (for Smalltalk), "smarty" (for Smarty), "sql" (for SQL), "tcl" (for TCL), "text" (for Text), "thinbasic" (for thinBasic), "tsql" (for T-SQL), "vb" (for Visual Basic), "vbnet" (for vb.net), "vhdl" (for VHDL), "visualfoxpro" (for Visual Fox Pro), "winbatch" (for Winbatch), "xml" (for XML), "xpp" (for X++), "z80" (for ZiLOG Z80 Assembler).
    • 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.
    • 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 type	You 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="bash" linenumbers="normal"> foo = "bar"; baz = "foz"; </code>	Code block with syntax highlighting for Bash source code and normal line numbers.
    <code language="bash" start="23" fancy="7"> foo = "bar"; baz = "foz"; </code>	Code block with syntax highlighting for Bash source code, line numbers starting from 23 and highlighted line numbers every 7th line.
