title: Changing navbar hover icon
body: <p>Currently I have a code example that function in a way that if the link on the navbar has sub-options, there is a small '+' sign next to the link. When the user hovers over the link, this changes to a '-' and shows the sub-options in a dropdown. What I want to do is change this to a sort of yellow 'v' shape (Stays static no matter if the user hovers or not) but I'm not sure how to do it.</p>
  
  <p>The code example I have is quite long and I know it's to do with the <code>a:before</code> and <code>a:after</code> parts of the CSS but I'm not sure exactly what I'd have to change. Any help would be greatly appreciated.</p>
