This is a plugin that will enable you to add alerts, info and similar chunks of text.
This is useful when creating tutorials and you want the reader to be notified of a change in code or something to check. Info blocks are used in technical Books when you want to point some information or you want the reader to read a part that is important to understand the next piece of code.
This is also suitable when you republish articles on your blog to inform the user on what has changed.
Info Blocks also allow you to change:
<ul>
<li>Background color</li>
<li>Text color</li>
