<p class="intro">XSL-FO output goes into blocks.</p>
<hr />

<h2>XSL-FO Pages, Flow, and Block</h2>

<p>&quot;Blocks&quot; of content &quot;Flow&quot; into &quot;Pages&quot; of the output media.</p>

<p>XSL-FO output is normally nested inside &lt;fo:block&gt; elements,&nbsp; 
nested inside &lt;fo:flow&gt; elements, nested inside &lt;fo:page-sequence&gt; elements:</p>

<table width="100%" border="1" class="ex" cellspacing="0">
  <tr>
    <td>
<pre>&lt;fo:page-sequence&gt;
  &lt;fo:flow flow-name=&quot;xsl-region-body&quot;&gt;
    &lt;fo:block&gt;
      &lt;!-- Output goes here --&gt;
    &lt;/fo:block&gt;
  &lt;/fo:flow&gt;
&lt;/fo:page-sequence&gt;</pre>
    </td>
  </tr>
</table>
<br />
<hr />

<h2>Block Area Attributes</h2>
<p>Blocks are sequences of output in rectangular boxes:</p>

<table width="100%" border="1" class="ex" cellspacing="0">
  <tr>
    <td>
<pre>&lt;fo:block
  border-width=&quot;1mm&quot;&gt;
This block of output will have a one millimeter border around it.
&lt;/fo:block&gt;</pre>
    </td>
  </tr>
</table>
<br />
Since block areas are rectangular boxes, they share many common area properties:

<ul>
	<li>space  before and space after</li>
	<li>margin</li>
	<li>border</li>
	<li>padding</li>
</ul>

<table border="1" cellpadding="0" cellspacing="0" width="60%" bgcolor="#ffffff">
<tr>
<td width="100%" align="center">space before<br />
</td>
</tr>
</table>
<table border="0" cellpadding="0" cellspacing="0" width="60%" bgcolor="#a0a0a0">
<tr>
<td width="100%" align="center">margin<br />
	<table border="0" cellpadding="0" cellspacing="0" width="95%" bgcolor="#b0b0b0">
	<tr>
	<td width="100%" align="center">border<br />
		<table border="0" cellpadding="0" cellspacing="0" width="90%" bgcolor="#d0d0d0">
		<tr>
		<td width="100%" align="center">padding<br />
			<table border="0" cellpadding="0" cellspacing="0" width="90%" bgcolor="#ffffff">
		    <tr>
			<td width="100%" align="center">
			<br /><br /><br />content<br /><br /><br /><br />
			</td>
			</tr>
			</table>

</td>
</tr>
</table>
<table border="1" cellpadding="0" cellspacing="0" width="60%" bgcolor="#ffffff">
<tr>
<td width="100%" align="center">space after<br />
</td>
</tr>
</table>

<p>The <b>space before</b> and <b>space after</b> is the empty space separating 
the block from the other blocks.</p>

<p>The <b>margin</b> is the empty area on the outside of the block.&nbsp; </p>

<p>The <b>border</b> is the rectangle drawn around the external edge of 
the area. It can have different widths on all four sides. It can also 
be filled with different colors and background images.</p>
<p>The <b>padding</b> is the area between the border and the content area.</p>
<p>The <b>content</b> area contains the actual content like text, 
pictures, graphics, or whatever.</p>
