Separators in Menu/Nav Bar

Thanks for the reply. I already removed Simple CSS as I am happy with a non-plugin way of adding CSS.

Regarding the site with sidebar menus, you can see I've temporarily put a dash in front of the menu items in the sidebar until I find a more elegant way to separate them: http://ecoja.com

Hmm how about something like this?

.widget ul.menu li {
    border-bottom: 2px solid #000000;
}

That worked well. Thank you so much for the great support.

You're welcome :)

Hi mates, can you please help me with a horizontal separator for the menu in this website?

And another thing that I have no ideia how to go about it, (and if it is going to look good,) there's any way to put this menu, the all background transparent until a person clicks on the menu icon or passes over it?

Thanks alot, Great Work

Can you open a new topic for your question?

Thanks :)
