<h3>Usage</h3>
To mark a text as spoiler, enclose the passage with [spoiler] and [/spoiler]. 
Example: 
 Spoiler: [spoiler]Bruce Willis is a ghost![/spoiler]
The result is shown in the screenshot section.
<h3>Customize</h3>
The language of the link text has to be changed in the pluginfile itself: wpSpoiler.php.
CSS can be used to style the spoiler box and the links. The spoiler-div is identified by the classname <code>spoiler_div</code>. 
The link’s class is <code>spoiler_link_show</code> or <code>spoiler_link_hide</code>, depending on the current state.
An example stylesheet code snippet:
<pre><code>/* wpSpoiler */
a.spoiler_link_show,
a.spoiler_link_hide {
 background-repeat: no-repeat;
 background-position: left center;
 padding-left: 18px;
}
a.spoiler_link_show {
 background-image: url(images/add.png);
}
a.spoiler_link_hide {
 background-image: url(images/delete.png);
}
div.spoiler_div {
 background-color: #ddd;
 margin-top: -10px;
 padding: 2px;
}
</code></pre>
