Congratulations! You have styled your text block using Schema.org dictionary.
You have converted a lot of information into a machine-readable format:
As you can see, even a small text like this could be enriched with a lot more details. Even if we consider them obious, we just defined the context of the article without any doubt, and search engines bot will thank us.
Example 4.3. Final HTML with microdata
<div itemscope="" itemtype="http://schema.org/Movie"> <h1 itemprop="name">Avatar</h1> <div itemprop="director" itemscope="" itemtype="http://schema.org/Person"> Director: James Cameron (born <time itemprop="birthDate" datetime="1954-08-16">August 16, 1954</time>) </div> <span itemprop="genre">Science fiction</span> <a itemprop="trailer" href="http://www.example.com/movies/avatar-theatrical-trailer.html"> Trailer </a> </div>
As last thing, why don't you try to convert the trailer link into a new itemtype block and style it?
