title: ckeditor and codesnippets plugin
body: <p>I'm baffled! I built ckeditor 4.13 using the online builder, and included the codesnippet plugin. Now when I chose the plugin within the editor from the toolbar it allows me to add the code under which ever language I choose, but the syntax highlighting doesn't work for all languages. For example CSS is not highlighted. The background of the chosen theme is there, but no highlighting. SQL queries are fine as are some others, but not CSS or PHP it would seem! </p>
  
  <p>Also, I'm editing in one place and then viewing the article on another place (pulling the article from a database). The styling is completely missing altogether when it's the article is viewed. I tried to find a CSS file which may contain the classes that had been attached to the snippets (such as language-php) but couldn't. I thought if I just linked to the CSS file in my header it would attach the styling...I was wrong!</p>
  
  <p>Any ideas how I can tackle this issue please? Google has brought nothing so far.</p>
