I have installed B2Evolution to my website folder and so far it works okay, but I want my blog to be presented as a single page on my existing website, and don't want the additional menus of "blog contact login" across the top. I was wondering if I can do this with css to simply hide the top menu bar.

FYI, I already tried adding style.css file into the file area of Home and putting the following code in there but it does not work

nav.sitewide_header {
  display: none;
}

I assume I need to make a copy of the skin and adapt it, but I was not sure if it will work. If someone has an easier way of doing this (a setting somewhere maybe?) then I would appreciate knowing how to do this.

Failing that is there a way to change the items on the top menu bar so it matches my website top menu bar at https://www.mdkberry.com ?
