Taxonomy term as node css class
Edit you node-type.tpl.php for this.

&lt;?php
    foreach($node-&gt;taxonomy as $term){
            $term_classes[] = $term-&gt;name;
    }
?&gt;


And print those classes in your node content wrapper.

&lt;div class="content &lt;?php print implode(' ', $term_classes); ?&gt;"&gt;
    &lt;?php print $content ?&gt;
&lt;/div&gt;
