DW Timeline: After making menu fixed can no longer see it because of Admin Toolbar

Hi,

I just recently installed the DW Timeline theme, and I needed a fixed menu. So I used the following code:

.nav-main, .no-cover .nav-main, .nav-main {
    position: fixed;
}

Here is the site link:

I am not able to properly navigate the website if I am logged in, so please help.

Nothing I seem to try is helping.

Thanks,
Alexandra

P.S. I have tried posting this question previously. Apparently ig either got deleted or it was not approved.
