     1= Using HTML in Wiki Text = 
     2 
     3Trac supports inserting HTML into any wiki context, accomplished using the HTML [wiki:WikiProcessors WikiProcessor]. 
     4 
     5HTML support is built-in, and does not require installing any additional packages. 
     6 
     7== How to Use HTML == 
     8To inform the wiki engine that a block of text should be treated as HTML, use the ''html'' processor.  
     9 
     10This example should explain: 
     11{{{ 
     12#!html 
     13<pre class="wiki">{{{ 
     14#!html 
     15&lt;h1 style="text-align: right; color: blue"&gt;HTML Test&lt;/h1&gt; 
     16}}}</pre> 
     17}}} 
     18 
     19Results in: 
     20{{{ 
     21#!html 
     22<h1 style="text-align: right; color: blue">HTML Test</h1> 
     23}}} 
     24 
     25Note that Trac sanitizes your HTML code before displaying it. That means that if you try to use potentially dangerous constructs such as Javascript event handlers, those will be removed from the output.  
     26 
     27Since 0.11, the filtering is done by Genshi, and as such, the produced output will be a well-formed fragment of HTML. In other words, this mean that you can no longer use two HTML blocks, one for opening a <div>, the second for closing it, in order to wrap arbitrary wiki text. 
     28The new way to wrap any wiki content inside a <div> is to use the ''div'' Wiki  processor: 
     29 
     30{{{ 
     31{{{ 
     32#!div class=important style="border: 2pt solid; text-align: center" 
     33This is the ''only'' way to go in Trac 0.11 
     34}}} 
     35}}} 
     36 
     37Results in: 
     38{{{ 
     39#!div class=important style="border: 2pt solid; text-align: center" 
     40This is the ''only'' way to go in Trac 0.11 
     41}}} 
     42 
     43Note that if you don't specify a CSS class, the `wikipage` class will be added, so that the special layout of headers is respected in the <div>. If you specify explicitly the padding property, you have to take this into account (tip: [http://getfirebug.com/ get FireBug]!). 
     44 
     45For spans, you should rather use the Macro call syntax: 
     46{{{ 
     47 Hello [[span(''WORLD'' (click [#world-anchor here]), style=color: green; font-size: 120%, id=world-anchor)]]! 
     48}}} 
     49 
     50Results in: 
     51 Hello [[span(''WORLD'' (click [#world-anchor here]), style=color: green; font-size: 120%, id=world-anchor)]]! 
     52 
     53 
     54== Images == 
     55If you want display an image inline, append the following: '''?format=raw''' after the file name.  For example, to display the Trac logo inline, use this syntax: 
     56 
     57{{{ 
     58 <img src="http://www.edgewall.org/gfx/trac_logo.png?format=raw" /> 
     59}}} 
     60 
     61{{{ 
     62#!html 
     63<img src="http://www.edgewall.org/gfx/trac_logo.png?format=raw" /> 
     64}}}
