The plugin renders a tag cloud using a professionally designed tag image as a background.
The plugin’s tag cloud is completely responsive and is correctly rendered in all browsers.
The primary application of this feature is through the “Cool Tag Cloud” widget, but you can also use the shortcode [cool_tag_cloud] to display the tag cloud anywhere where shortcodes are supported.
Here is the list of parameters that can be used with the shortcode, each with its own set of potential values (which are separated by the | symbol):
<ul>
<li><code>style="default|silver|green|red|blue|brown|purple|cyan|lime|black"</code></li>
<li><code>font_family="Arial, Helvetica, sans-serif"</code></li>
<li><code>smallest="10"</code></li>
<li><code>largest="10"</code></li>
<li><code>align="left|right"</code></li>
<li><code>font_weight="normal|bold"</code></li>
<li><code>text_transform="none|uppercase|lowercase|capitalize"</code></li>
<li><code>number="20"</code></li>
<li><code>order_by="name|count"</code></li>
<li><code>order="ASC|DESC|RAND"</code></li>
<li><code>taxonomy="post_tag"</code></li>
<li><code>nofollow="yes|no"</code></li>
<li><code>animation="yes|no"</code></li>
<li><code>on_single_display="global|local"</code></li>
<li><code>on_archive_display="all|children|siblings|descendants"</code></li>
<li><code>exclude="1,2,3"</code></li>
<li><code>include="1,2,3"</code></li>
</ul>

Cool Tag Cloud

This came as a blessing when I had written some custom code to show a custom Taxonomy cloud on sidebar. The options to customize are so cool, and I love the option to either show the taxonomy related to a post on a Single post page or all tags, that makes it so versatile. Thanks so much to the author.

Very very Useful

Tag Cloud Widget adds a simple tag cloud widget that you can use anywhere on your blog. This plugin looks at all your tags and displays them in a widget. The more times a tag is used, the larger the tag is.
Each tag is a link to the tag page (e.g. http://your-site.com/tag/your-tag). This will help with SEO.
Currently, there aren’t any options to customize the tag cloud. It should work well out of the box. In the future, there may be options to customize the widget.
