title: Hover with span and css3
body: <p>I just created a hover for my menu, but I have a problem with the "span". </p>
  
  <p>I cant't set the width for 100%, so that I will see the all text from the button. 
  I know that it is possible to set the width rigidly but it should be inherit from the text width.</p>
  
  <p>Can anyone help me with that?</p>
  
  <p>Thanks.</p>
