							<p>When generating <a href="/glyph/book/text_editing/topics.html#topics">topic</a>-based outputs, Glyph uses <em>layouts</em> to render topics as standalone documents. By default, the following two layout are used:</p>
<ul>
	<li><code>topic</code> &#8212; used to render standard topics.</li>
	<li><code>index</code> &#8212; used to render the index page of your document.</li>
</ul>
<p>Layouts are nothing more than &#8220;fancy&#8221; Glyph macros defined using the Glyph language (i.e. by using <a href="/glyph/book/extending/interpreting.html#rewriting">macro rewriting</a>) within a single <code>.glyph</code> file.</p>
<section class="section">
<header><h1 id="h_84">Topic Layout</h1></header>
<p>The default layout used to render all web topics (the layout used for web5 topics is very similar) is defined as follows:</p>
	<div class="CodeRay">
  <div class="code"><pre><span class="no"> 1</span> document[
<span class="no"> 2</span>   head[
<span class="no"> 3</span>     style[default.css]
<span class="no"> 4</span>   ]
<span class="no"> 5</span>   body[
<span class="no"> 6</span>     @class[topic]
<span class="no"> 7</span>     section[
<span class="no"> 8</span>       @title[{{title}}]
<span class="no"> 9</span>       @id[{{id}}]
<span class="no"><strong>10</strong></span>       navigation[{{id}}]
<span class="no">11</span> {{contents}}
<span class="no">12</span>       navigation[{{id}}]
<span class="no">13</span>     ]
<span class="no">14</span>   ]
<span class="no">15</span> ]</pre></div>
</div>

	<p>Note that it takes the following attributes, passed automatically by Glyph when processing each topic:</p>
<ul>
	<li><code>title</code> &#8212; the title of the topic.</li>
	<li><code>id</code> &#8212; the ID of the topic.</li>
	<li><code>contents</code> &#8212; the body of the topic.</li>
</ul>

</section>
<section class="section">
<header><h1 id="index_layout">Index Layout</h1></header>
<p>The default layout used to render the web index page (the layout used for the web5 index is very similar) is defined as follows:</p>
	<div class="CodeRay">
  <div class="code"><pre><span class="no"> 1</span> document[
<span class="no"> 2</span>   head[
<span class="no"> 3</span>     style[default.css]
<span class="no"> 4</span>   ]
<span class="no"> 5</span>   body[
<span class="no"> 6</span>     @class[topic]
<span class="no"> 7</span>     halftitlepage[
<span class="no"> 8</span>       title[]
<span class="no"> 9</span>       subtitle[]
<span class="no"><strong>10</strong></span>       author[]
<span class="no">11</span>     ]
<span class="no">12</span>     frontmatter[
<span class="no">13</span>       toc[]
<span class="no">14</span>     ]
<span class="no">15</span>   ]
<span class="no">16</span> ]</pre></div>
</div>

	<p>Index layouts do not take any attribute or parameter (basically because they are used to produce only one page).</p>

</section>
<section class="section">
<header><h1 id="h_86">Creating a Custom Layout</h1></header>
<p>To create a custom layout, proceed as follows:</p>
<ul>
	<li>Create a <code>.glyph</code> file in the <code>lib/layouts</code> directory, within your project, e.g. <code>mytopic.glyph</code></li>
	<li>Add the layout code, making sure (for topic layouts) that all the attributes (<code>title</code>, <code>id</code>, <code>contents</code>) are specified correctly.</li>
	<li>Set the <code>output.*.layouts.topic</code> setting to the name of the new layout (<code>mytopic</code>).</li>
</ul>
	<aside class="tip">
<span class="note-title">Tip</span>You can override which layout to use on a specific topic by specifying it in a <code>@layout</code> attribute.
