body: <p>I'm customizing a Wordpress Theme and i have stucked in add a custom class to the "the_excerpt()". </p>
  
  <p>I have searched on the web for this function, but nothing is specific to add a custom class.</p>
  
  <p>Hm, i've tried the "get_the_excerpt", but this one doesn't work (returns nothing).</p>
