I am working on The Return To Menu Tab

The original code was,

<li><a href="#home" class="scroll">Return to menu</a></li>

I am looking to center the text & scroll as before.
Just centering the text works ok but my code below for both does not scroll,can you advise where i went wrong please.

<li class="licenter scroll"><a href="#home">Return to Menu</a></li>

Now sorted.

Added the code below.

<li class="licenter"><a href="#home" class="scroll">Return to Menu</a></li>
